**639The sole issue in this certified appeal is whether the trial court made an improper comparison between the respondent mother, Marjorie H., and Paula M., the therapeutic foster mother of the respondent's minor children, James O., Jr., and Jolene O., during the adjudicative phase of its judgment terminating the respondent's parental rights.1 The respondent2 appeals from the judgment of the Appellate Court affirming the trial court's decision to terminate her parental rights as to James and Jolene, and to appoint the petitioner, the Commissioner of Children and Families, as their statutory parent. In re James O., 160 Conn.App. 506, 508, 127 A.3d 375 (2015). The respondent claims that the Appellate Court improperly affirmed the trial court's judgment terminating her parental rights pursuant to General Statutes (Rev. to 2013) § 17a-112 (j)(3)(B)3
**640because the trial court engaged in an improper comparison between the parenting abilities of the respondent and those of Paula M. to support the court's conclusion that the respondent had failed to reach a sufficient level of personal rehabilitation. We disagree and affirm the judgment of the Appellate Court.
The following facts, which the trial court found by clear and convincing evidence, and procedural history are relevant to the resolution of this appeal. During the spring of 2011, staff at James' school became concerned with the fact that James, then seven years old, was making suicidal and homicidal statements and was physically harming himself. The school staff attempted to work with the respondent to *1150secure a psychological evaluation and appropriate treatment for James.
Around the same time, James' therapist reported that James disclosed to her that he "had a secret, that he [heard] voices, and that he hurts himself at home." The therapist also recommended that James receive a psychological evaluation, but the respondent refused to allow an evaluation unless the school paid for both children to be evaluated. The therapist did not believe that the respondent grasped the seriousness of James' condition.
School staff also referred James for Intensive In-Home Child and Adolescent Services (in-home services). The respondent refused to allow the services in her home. The respondent removed the children from the school, intending to homeschool them, claiming **641that James had psychotic episodes only at school and would behave normally at home. During 2011, the children's school made a referral for both children to the Department of Children and Families (department).
On June 9, 2011, the petitioner filed neglect petitions and sought and received an order of temporary custody as to both children based on the children's exposure to substance abuse and domestic violence, evidence of James' serious mental health issues, the failure of both parents; see footnote 2 of this opinion; to follow through with recommended services for both children, and the withdrawal of the children from school and the resulting lack of visibility in the community. The petitioner included as an additional ground educational neglect arising from the children having missed thirty days of school.
At the time of their removal from the respondent's custody, both children displayed highly disturbing behaviors. After removal, outside the presence of his parents, James disclosed to Danbury Hospital staff that he was hearing voices and that his head was telling him to do things. James threatened to harm another child in his first foster home, stating that he would kill and eat the child. Jolene, then six years old, displayed sexualized behavior including frequent public masturbation, talk about sex, and attempts to engage other children, including her brother, in inappropriate sexual acts. Based on Jolene's conduct, her first foster mother questioned whether Jolene had a history of sexual abuse.
Despite Jolene's behavior, the respondent and the department reached an agreement whereby the order of temporary custody would remain in effect for James, who was to be hospitalized at Yale-New Haven Hospital for psychiatric treatment, while the order would dissolve for Jolene on June 23, 2011, upon the condition that the respondent would take Jolene to therapy. On **642June 24, 2011, during her therapy in-take interview, Jolene disclosed to the therapist that her father had physically abused her and inappropriately touched her. The department invoked a ninety-six hour hold and removed Jolene from the respondent's custody for the second time.
While at Yale-New Haven Hospital, James continued to make suicidal statements and homicidal statements about killing and eating other children. The respondent attributed his conduct to a cartoon he watched on television. The hospital staff also reported bizarre interactions between James and Jolene. They observed that the parents did not set appropriate limits on the children's behavior.
The department placed James and Jolene in a Safe Home placement, which would provide more stability, allow the children to receive mental health services directly at the facility, and allow the department to more directly assess their needs. While the children were at the Safe Home, the department determined *1151that the children would need a family that would understand and be able to handle their ongoing behavioral issues. James was still having suicidal ideation, had a tendency to fixate, and had a fragile emotional state. In addition to sexual behavior, Jolene was reluctant to bathe, was very hyperactive and aggressive, cursed and made threats to others. She also exhibited excessive animal behaviors, at times walking on all fours and making animal noises, and had a skewed sense of reality. Safe Home staff described her "as one of the most traumatized children they have seen."
The department determined that the children needed to be placed in a therapeutic foster home with a caregiver who could understand and manage their behaviors and provide more intensive therapeutic support. In October, 2011, the department placed the children with **643Paula M., a licensed therapeutic foster care provider. The trial court described Paula M. as "part of a team that includes [the department], the children's therapists, and Wheeler Clinic...." Paula M. met with the children's therapists weekly, attended special education planning and placement meetings, informed the children's therapists of issues that arose with the children, and helped to implement at home what the children learned in therapy, such as specific coping skills when they became anxious. Paula M. also worked with the in-home service providers in the home twice weekly, once with James and a second time without the children present to train her to work with James.
Beginning in October, 2011, Jolene was referred for treatment to the Child Abuse Treatment Services Program at Klingberg Family Centers. That program uses trauma focused cognitive behavioral therapy to assist children who have experienced physical or sexual abuse or have witnessed domestic violence. At the time of the referral, the therapists were not able to begin trauma focused cognitive behavioral therapy with Jolene because the respondent refused to give her consent.
In February, 2012, both children separately made disclosures of sexual abuse to Paula M. Using the coping skills he learned in therapy, James wrote a narrative that included numerous explicit descriptions of a variety of sexual contact involving James, Jolene, and their parents. While attending church with Paula M., Jolene asked for paper and a pencil and then drew figures of what looked like a child and an adult, including one that suggested sexual activity between the two figures. Paula M., in her capacity as a mandatory reporter, provided a copy of Jolene's drawings to the department. Jolene subsequently disclosed to her therapist that the drawings depicted her abuse.
**644On June 19, 2012, after the trial court had already taken evidence in the contested neglect petitions over several days, the respondent and the children's father entered nolo contendere pleas to neglect. The court adjudicated the children neglected and committed them to the custody of the petitioner.
Because of Jolene's commitment to the petitioner's custody, she was able to begin trauma focused cognitive behavioral therapy. The goal of her therapy was treatment of the symptoms of trauma and abuse, rather than investigation of alleged sexual abuse. Jolene was diagnosed with post-traumatic stress disorder (PTSD). By June, 2013, Jolene exhibited a successful reduction in trauma symptoms, developed coping and relaxation skills, and, as a result, was successfully discharged from the trauma focused cognitive behavioral therapy program.
James also exhibited a marked improvement to his therapists. At the time of his initial commitment, James presented with *1152suicidal ideation, hypervigilance, high anxiety, frequent tantrums, a great deal of fear, difficulty sleeping, and paranoia. He was diagnosed with PTSD and autism. By the time his most recent therapist was assigned to him in June, 2013, he was no longer presenting with suicidal ideations and his anxiety had decreased significantly. James continued to exhibit issues with boundaries and social skills, which caused behavioral issues for him at school. James' therapist noted that he required the lessons and skills he was taught in therapy to be mirrored in the parenting he received at home, with a caregiver who is firm, but also very calm, warm, and supportive of him.
At the time that the respondent entered her nolo contendere pleas to neglect, the respondent agreed to specific steps to facilitate reunification with James and Jolene, including attending individual therapy for the **645purpose of gaining insight into domestic violence and its impact on the children, improving her communication skills, learning how to problem solve without escalating to violence, and understanding appropriate boundaries with respect to sexual abuse and the needs of children who have disclosed sexual abuse.
The respondent declined to see a department recommended therapist and instead selected one who disagreed with most of the treatment goals outlined in the court-ordered specific steps. Rather than work with the respondent to address the steps provided by the court, the psychologist focused, instead, on discrediting the children's reports of sexual abuse. The trial court found that while the respondent attended individual therapy, she failed to advance any of the goals of such therapy as agreed to in her specific steps.
During the children's commitment, the department provided the respondent with supervised visitation with the children and parent education support, as well as assistance with transportation to visitations. The respondent worked with two parent educators along with visitation supervisors. Both parent educators attempted to provide feedback to the respondent on her interactions with the children, but the respondent reacted negatively to any perceived criticism, at times yelling at the educators or the department social worker. The parent educators observed that the respondent continued to have difficulty setting appropriate limits for the children or setting consequences if the children failed to comply with limits.
As part of her specific steps, the respondent was also required to improve her communication skills in order to allow her to effectively communicate and work with the children's therapy providers. The respondent was permitted, and encouraged, to communicate with the **646children's therapists and school social workers and psychologists. The respondent declined to do so.
The respondent was also required to take steps to acknowledge her role in the removal of her children. The respondent focused, instead, on denying the allegations of sexual abuse. She also failed to acknowledge the disturbing behavior that initially led to her children's removal or the impact of substance abuse and domestic violence on the children. While she acknowledged that the children's father had a substance abuse issue and could be violent, she minimized the impact that his behavior had on the children and did not acknowledge her own propensity for violence. According to the respondent, the father's substance abuse and violence would not impact the children in the future because she was then divorced from the father and he did not have visitation rights under the dissolution agreement. The trial court found, however, that the respondent and the father entered into a visitation agreement in order for it to appear to *1153the department that the respondent was protecting the children when, in reality, the respondent and the father still had a relationship and he was often present in her home.
On April 24, 2013, the petitioner, pursuant to § 17a-112 (j)(3)(B), filed a petition to terminate the respondent's parental rights as to both children on the ground that she had failed to achieve the degree of personal rehabilitation that would encourage the belief that within a reasonable time, considering the age and particular needs of the children, she could assume a responsible position in their lives.
On November 13, 2014, the trial court terminated the respondent's parental rights as to both children. The court found that the department had made reasonable efforts to reunify the respondent with both children, but that she failed to acknowledge the children's disturbing **647behavior and her role in causing their removal. The court further found that the respondent had failed to achieve a reasonable level of rehabilitation. The court finally found that it was in the best interest of the children for the court to terminate the respondent's parental rights.
On March 3, 2015, the respondent appealed the trial court's termination of her parental rights to the Appellate Court, claiming that the court had made an improper comparison between the respondent and Paula M. in the adjudicative portion of its memorandum of decision.4 Thereafter, the Appellate Court affirmed the judgment of the trial court. In re James O., supra, 160 Conn.App. at 507, 528, 127 A.3d 375. The Appellate Court "construe[d] the language relied on by the respondent, not as making a direct comparison between the respondent and Paula M., so much as clarifying that the children needed and continued to need an environment that is calm, in which their needs are understood, and in which their caregiver can manage their anxiety in an appropriate manner." Id., at 520, 127 A.3d 375. This appeal followed.
The respondent claims that the Appellate Court improperly held that the trial court did not engage in an improper comparison between the parenting abilities of the respondent and Paula M. in the adjudicative portion of its memorandum of decision terminating the respondent's parental rights. In the respondent's view, certain language in the trial court's memorandum of decision evidences its improper reasoning. The respondent **648contends that any comparison at all between a parent and a foster parent is a violation of Practice Book § 35a-7 (b),5 should be presumed to influence the trial court's determination in the adjudicatory phase, and requires reversal.6 *1154The petitioner agrees that if the trial court based its determination that the respondent had failed to reach an adequate level of rehabilitation on a finding that Paula M. was a better parent or was a preferable parent to the respondent, that would be a due process violation and grounds for reversal. The petitioner contends that, when read within the context of the entire memorandum of decision, the challenged language does not constitute a comparison between the respondent and Paula M. Rather, the court was discussing the specific needs of the children as a predicate to considering the respondent's ability to meet those needs. Within this context, the examination of Paula M.'s role in the children's therapy and the environment of the foster home are merely evidence of what is actually required to meet the children's specific needs, which is a necessary consideration during the adjudicative phase of a termination of parental rights determination when the ground for termination is a failure to rehabilitate. The petitioner further emphasizes that the respondent failed to reach even a minimally sufficient ability to assume a role as an appropriate caregiver and refused to even acknowledge the children's particular needs. Therefore, according **649to the petitioner, the court did not make an improper comparison that would require reversal. We agree with the petitioner.
We first set forth the applicable standard of review and general principles. "The interpretation of a trial court's judgment presents a question of law over which our review is plenary.... As a general rule, judgments are to be construed in the same fashion as other written instruments.... The determinative factor is the intention of the court as gathered from all parts of the judgment.... Effect must be given to that which is clearly implied as well as to that which is expressed.... The judgment should admit of a consistent construction as a whole.... If there is ambiguity in a court's memorandum of decision, we look to the articulations that the court provides."7 (Citations omitted; internal quotation marks omitted.) Olson v. Mohammadu, 310 Conn. 665, 682, 81 A.3d 215 (2013).
"In order to terminate a parent's parental rights under § 17a-112, the petitioner is required to prove, by clear and convincing evidence, that: (1) the department has made reasonable efforts to reunify the family; General Statutes § 17a-112 (j)(1) ; (2) termination is in the best interest of the child; General Statutes § 17a-112 (j)(2) ; and (3) there exists any one of the seven grounds for termination delineated in § 17a-112 (j)(3)." (Internal quotation marks omitted.) In re Melody L., 290 Conn. 131, 148-49, 962 A.2d 81 (2009), overruled in part on other grounds by **650State v. Elson, 311 Conn. 726, 746-47, 754, 91 A.3d 862 (2014). When the petitioner seeks to terminate a parent's parental rights on the ground that the parent has failed to rehabilitate, "[t]he trial court is required, pursuant to § 17a-112, to analyze the [parent's] rehabilitative status as it relates to the needs of the particular child, and further ... such rehabilitation must be foreseeable within a reasonable time." (Emphasis added; internal quotation *1155marks omitted.) In re Shane M., 318 Conn. 568, 585, 122 A.3d 1247 (2015). Therefore, the trial court must first determine the needs of the particular child before determining whether a parent has achieved a sufficient rehabilitative status to meet those needs. See, e.g., In re Shyliesh H., 56 Conn.App. 167, 175, 743 A.2d 165 (1999) (respondent's rehabilitative status viewed in light of child's medical and psychiatric conditions).
Turning to the ability of a trial court to consider evidence of the abilities of a foster parent when adjudicating a petition to terminate parental rights, we have recognized that such determinations "are particularly vulnerable to the risk that judges or social workers will be tempted, consciously or unconsciously, to compare unfavorably the material advantages of the child's natural parents with those of prospective adoptive parents and therefore to reach a result based on such comparisons rather than on the statutory criteria."8 In re Juvenile Appeal (Anonymous ), 177 Conn. 648, 672-73, 420 A.2d 875 (1979). " 'It is ... essential, in considering a petition to terminate parental rights, to sever completely the issues of whether termination is statutorily warranted and whether a proposed adoption is desirable. Although petitions for termination are presumably **651seldom brought unless prospective adoptive parents are available, there still must be a two-step process to determine, first, the threshold question of whether cause for termination ... has been proved.' [Id., at 673, 420 A.2d 875 ]; see also Matter of Corey L. v. Martin L., 45 N.Y.2d 383, 391, 380 N.E.2d 266, 408 N.Y.S.2d 439 (1978). Accordingly, we have held that '[o]nly if a ground for termination exists may the suitability and circumstances of adoptive parents, in an appropriate proceeding, be considered.' In re Juvenile Appeal (Anonymous ), 181 Conn. 638, 645, 436 A.2d 290 (1980)." In re Baby Girl B., 224 Conn. 263, 275, 618 A.2d 1 (1992).
We do not permit foster or preadoptive parents to intervene in termination proceedings because to do so would "permit them to shape the case in such a way as to introduce an impermissible ingredient into the termination proceedings." (Internal quotation marks omitted.) Id., at 278, 618 A.2d 1. We have never held, however, that a foster parent may not testify during the adjudicative phase of a termination proceeding or that a trial court may not consider evidence that arises within the context of a foster placement that is relevant to one of the statutory grounds raised for termination of parental rights. See In re Juvenile Appeal (Docket No. 10718 ), 188 Conn. 259, 266-67, 449 A.2d 165 (1982) (Shea, J., dissenting) ("Unquestionably the foster parents ... would have been permitted to testify, as the foster mother did, during the adjudicative phase of the termination proceedings. The majority opinion does not question that her testimony was highly relevant to the grounds alleged for termination of parental rights."); see also In re Anthony H., 104 Conn.App. 744, 752, 936 A.2d 638 (2007) (trial court noted, and Appellate Court did not question, that child needed "a substantial amount of structure, which his prior therapeutic foster homes were able to provide" within context of specific needs of child), cert. denied, 285 Conn. 920, 943 A.2d 1100 (2008) ;
**652In re Vincent D., 65 Conn.App. 658, 665-66, 783 A.2d 534 (2001) (foster *1156parent may not intervene in adjudicative phase of proceeding, but may be called as witness for petitioner on issues that may be considered during dispositional phase); In re Shyliesh H., supra, 56 Conn.App. at 171-72, 743 A.2d 165 (child's interactions with foster mother, in contrast to interactions with others, were evidence of psychiatric condition relevant to specific needs of child in adjudicative phase).
We must determine, therefore, whether the trial court properly considered evidence of the children's foster placement as relevant to an aspect of an adjudicatory ground for termination, or rather, as the respondent contends, it improperly reasoned that termination was warranted because Paula M. was a better or preferable parent than the respondent. Looking to the trial court's memorandum of decision, the court made the following findings that are relevant to this determination.
At the outset of its analysis on the respondent's failure to rehabilitate, the trial court quoted law stating that rehabilitation must be assessed with reference to the needs of the particular children at issue. Thereafter, the court emphasized that "[p]ivotal to this court's findings and the starting point for its analysis is the ... determination of the age and needs of James ... and Jolene." The court went on to describe the children's history of disturbing behavior, the respondent's continuing failure to acknowledge that behavior, and her role in causing it, opining that such failure was an "enormous impediment to reunification."9
**653The trial court next noted that "[t]he most credible, persuasive and reliable evidence of the children's needs is the testimony of the children's therapists, as manifested by the therapeutic approach they utilized and the importance of the caregivers' role in helping the children address and heal from the trauma they have endured." The court went on to describe the goals of the children's therapy and the roles of various therapy providers, including Paula M., in documenting any disclosures made by the children.
The next paragraph of the memorandum of decision is the subject of this appeal. In its entirety, it reads: "More important than the disclosures, however, is the clear and convincing evidence that the children have made extraordinary progress while living with Paula M., in an environment that is calm and understanding of the children's needs. As both therapists have made clear, the children have needed a caregiver who is calm, patient, able to set appropriate limits, willing to participate intensively in the children's therapy, and able to help the children with coping skills to manage their anxiety. The children have also needed someone who would believe their statements about the source of their trauma. [The children's therapist] credibly testified that the [trauma focused cognitive behavioral therapy ] model requires that a child be understood and treated in the context of their living environment. As the children's progress, relationship and work with Paula M. makes clear, the process of healing and recovery must also occur in a home environment *1157which the children have come to learn is safe and caring. Given Paula M.'s training and participation in therapy sessions, it is clear that this process cannot be limited to the one hour per week session that a child has, even with a trusting therapist. In contrast, [the respondent] is volatile and prone to violence, unable to set appropriate limits, unwilling to talk with the children's therapists and, therefore, unable **654to help them use coping skills to manage their anxiety and ultimately, unwilling to believe the children's statements regarding the trauma. In short, [the respondent] has none of the qualities [that] the children have required to stabilize and to continue to heal from the traumas they experienced while in their parents' care."
In the very next paragraph, the trial court reiterates that "the most credible and reliable evidence of the age and needs of the children, around which the [respondent's] rehabilitation is evaluated and assessed, necessarily comes from the work done by the children's therapeutic team, which includes the work of [Paula M.], the reliable and credible evidence regarding the children's severely disturbed behaviors and the degree to which the children's behaviors have greatly stabilized. The evidence that the children have, in fact, made such dramatic improvement in their functioning, under the conditions which their therapists and caregivers have been able to dictate and nurture, is itself confirmation of the expertise, skill and knowledge of these professionals." Thereafter, the trial court concluded the adjudicatory phase, finding "that the petitioner has met its burden, by clear and convincing evidence, [that] the [respondent has] failed to rehabilitate, given the age and needs of both children."
After considering the challenged portion of the memorandum of decision within the context of the trial court's overall analysis, we conclude that the court's adjudicative findings are appropriately centered on the specific needs of James and Jolene, a necessary consideration when determining whether a respondent has failed to rehabilitate. The beginning of the court's analysis makes it abundantly clear that the court is focused on James' and Jolene's particular needs, as seriously traumatized children, and is assessing the respondent's state of rehabilitation with reference to those needs. Additionally, the court twice indicates its belief that **655the best evidence of those needs is an examination of the children's course of therapy and its positive results, including the roles of their therapists and caregivers. In essence, the court recognized that, whoever the children's caregiver is, he or she necessarily must play an important role in helping the children continue to address and heal from their trauma.
It is within this overall framework that the trial court made the findings that the respondent alleges are an improper comparison of the respondent and Paula M. Here, while the court does specifically discuss Paula M., it does so in light of what the children's therapists have testified are the specific needs of the children. The court notes generally that, "[a]s both therapists have made clear, the children have needed a caregiver who is calm, patient, able to set appropriate limits, willing to participate intensively in the children's therapy, and able to help the children with coping skills to manage their anxiety. The children have also needed someone who would believe their statements about the source of their trauma." (Emphasis added.) The court is basing the level of care needed not on what Paula M. is providing to the children, but on what the children's therapists have testified the children need from a caregiver. Although the court then discusses the progress made by the children while they were living with Paula M., we interpret that discussion as merely evidence that supports *1158the recommendations of the children's therapists as to the children's particular needs. In short, the improvements seen from Paula M.'s implementation of the therapeutic recommendations proved the need for and efficacy of the recommended approach. Importantly, the court never opined that only Paula M. could meet the children's needs or that Paula M. ought to be the person to meet their needs. The court merely explained that, when the children were in an environment **656that did meet their particular needs, they were able to make extraordinary progress.
Appropriately, the trial court then began its assessment of the respondent's ability to meet the particular needs of the children. The respondent advocates that the sentence beginning "[i]n contrast" evidences an improper comparison of the abilities of the respondent and those of Paula M. Reading that sentence in context, however, we disagree. Rather, the language following "[i]n contrast" directly parallels the language the court previously had used to describe generally the qualities of a caregiver who would meet the children's particular needs. In establishing the children's particular needs, the court found that "the children have needed a caregiver who is calm, patient, able to set appropriate limits, willing to participate intensively in the children's therapy, and able to help the children with coping skills to manage their anxiety ... [and] also ... someone who would believe their statements about the source of their trauma." Then in evaluating the respondent, the court found that, "[i]n contrast, [the respondent] is volatile and prone to violence, unable to set appropriate limits, unwilling to talk with the children's therapists and, therefore, unable to help them use coping skills to manage their anxiety and ultimately, unwilling to believe the children's statements regarding the trauma." It is clear that the contrast drawn by the court is between the qualities of a caregiver who meets the particular needs of the children, as described by the children's therapists, and those of the respondent.
Most importantly, after comparing the needs of the children with the abilities of the respondent, the trial court found that the respondent "has none of the qualities the children have required to stabilize and to continue to heal from the traumas they experienced while in their parents' care." (Emphasis added.) Quite simply, the court found that the respondent did not have the **657minimum ability to meet her children's particular needs and refused to even acknowledge what those needs were. While we are sensitive to the risks of a court comparing the abilities of a natural parent who can meet the basic needs of her children with the abilities of a foster parent who is more capable of meeting those needs and then making an adjudicatory determination based on who can better meet the needs of the particular children, those risks do not materialize when a court has found that a respondent has failed to achieve any level of rehabilitation and has none of the qualities necessary to meet the needs of the particular children.10 *1159Therefore, because the trial court found that the respondent had none of the qualities necessary to meet her children's needs, we conclude that the court did not improperly compare the abilities of the respondent and Paula M. in making its finding during the adjudicatory phase that the respondent failed to achieve a reasonable degree of rehabilitation.
The judgment of the Appellate Court is affirmed.
In this opinion PALMER, EVELEIGH and ESPINOSA, Js., concurred.
McDONALD, J., with whom ZARELLA and ROBINSON, Js., join, concurring.
A complete, contextual **658review of the trial court's memorandum of decision compels the conclusion that the court improperly compared the superior parental attributes of the foster mother, Paula M., with the wanting parental attributes of the respondent, Marjorie H., the mother of the minor children, James O., Jr., and Jolene O. Although I fully acknowledge that there is nothing in the record that would suggest that the trial court intended to draw that comparison, the plain words contained in the memorandum of decision reveal that, at the very least, it unconsciously did so. Regardless of that error, the trial court's findings as to the respondent, in and of themselves, require affirmance of the judgment.
As the majority properly recognizes, it is "essential, in considering a petition to terminate parental rights, to sever completely the issues of whether termination is statutorily warranted and whether a proposed adoption is desirable." (Internal quotation marks omitted.) In re Baby Girl B., 224 Conn. 263, 275, 618 A.2d 1 (1992). This is so because petitions "for termination of parental rights are particularly vulnerable to the risk that judges or social workers will be tempted, consciously or unconsciously, to compare unfavorably the material advantages of the child's natural parents with those of prospective adoptive parents and therefore to reach a result based on such comparisons rather than on the statutory criteria." In re Juvenile Appeal (Anonymous ), 177 Conn. 648, 672-73, 420 A.2d 875 (1979).
The requirement that the trial court conduct a hearing on a petition for termination of parental rights in two distinct phases-the adjudicatory phase, at which the trial court determines whether a statutory ground for termination of parental rights exists, and the dispositional phase, at which the trial court determines whether termination is in the best interest of the child; In re Shane M., 318 Conn. 568, 582-83 n. 12, 122 A.3d 1247 (2015) ;-is intended to safeguard against such **659improper considerations tainting the threshold inquiry. Accordingly, during the adjudicatory phase, it is per se improper for a trial court to compare the attributes of a natural parent with those of a prospective parent.1 In re Baby Girl B., supra, 224 Conn. at 280, 618 A.2d 1.
In the present case, the trial court's memorandum of decision was divided into four substantive parts: general findings of fact, a determination of whether the Department of Children and Families made reasonable efforts to reunify the respondent's family, a determination on the adjudicatory matter, and a determination on the dispositional matter. The court made specific findings of fact in support of each part. In the part resolving the adjudicatory matter, it clearly was proper for the trial court to analyze the respondent's rehabilitative *1160status in relationship to the needs of her children. See In re Shane M., supra, 318 Conn. at 585, 122 A.3d 1247 ; see, e.g., In re Shyliesh H., 56 Conn.App. 167, 173, 743 A.2d 165 (1999). The court, however, also found certain facts that had no bearing on that essential issue. The court found that Paula M. and a social worker were "individuals whom the children deeply trust" and observed that they "care greatly for these children and have therefore earned the trust of these very emotionally fragile and otherwise guarded children...." The court also found that the "children want to remain in Paula M.'s home and be adopted by [her]...." The court further concluded that "the children have made extraordinary progress while living with Paula M., in an environment that is calm and understanding of the children's needs.... As the children's progress, relationship and work with Paula M. makes clear, the process of healing and recovery must also occur in a home environment which the children have come to learn is safe and caring." The court then stated: "Given Paula M.'s training and **660participation in therapy sessions, it is clear that [the therapeutic] process cannot be limited to the one hour per week session that a child has, even with a trusting therapist. In contrast, [the respondent] is volatile and prone to violence, unable to set appropriate limits, unwilling to talk with the children's therapists and therefore, unable to help them use coping skills to manage their anxiety and ultimately, unwilling to believe the children's statements regarding the trauma." (Emphasis added.) I must take the trial court's unambiguous comparison at face value. Whether this was a conscious comparison by the court or an inartful choice of words to compare the respondent to Paula M., the plain language of its decision evidences that such a comparison was made.
The trial court's findings in its introductory part of the decision, although not limited to the issue in the adjudicatory phase, lend further support to this conclusion. See Olson v. Mohammadu, 310 Conn. 665, 682, 81 A.3d 215 (2013) (determinative factor when interpreting trial court's memorandum of decision "is the intention of the court as gathered from all parts of the judgment" [internal quotation marks omitted] ). The court repeatedly recited evidence discussing the positive attributes of Paula M.: "Paula M. attended therapy consistently every week and embraced as much education as possible in order to understand and help Jolene and [James] through their symptoms," and Mimi Akhand, James' therapist, observed "that the foster mother must be both firm with [James] but also very calm, warm and supportive of him.... Akhand noted that [Paula M.] is very skilled in this way and is also very good at processing with [James] his conduct when he misbehaves.... Akhand described [Paula M.] as being very understanding and very patient with [James]." While these findings can be construed as implicitly addressing the children's needs, they expressly emphasize **661Paula M.'s positive attributes. The absence of any reference to these facts in the dispositional part of the decision, along with the presence of similar references in the adjudicatory part of the decision, further demonstrates that Paula M.'s attributes influenced the court's decision in the adjudicatory phase.
I recognize that certain statements read in isolation might be subject to an alternative interpretation, but the totality of the statements and the clear expression of comparison-"In contrast"-compel the conclusion that the trial court improperly compared Paula M. with the respondent. I would therefore conclude that the trial court improperly injected the dispositional issue of the children's best interests analysis into the adjudicatory phase of its decision.
*1161This concern, unfortunately, is not limited to the present case. The Appellate Court has repeatedly addressed similar claims, but ultimately construed language that is susceptible to suggesting a comparison in the manner that the majority does in the present case. See, e.g., In re Gabriella A., 154 Conn.App. 177, 191-94, 104 A.3d 805 (2014) (court allegedly considered best interest of child in adjudicatory phase), aff'd on other grounds, 319 Conn. 775, 777, 127 A.3d 948 (2015) ; In re Brian T., 134 Conn.App. 1, 18-21, 38 A.3d 114 (2012) (same); In re Zion R., 116 Conn.App. 723, 736-39, 977 A.2d 247 (2009) (same); In re Janazia S., 112 Conn.App. 69, 93-96, 961 A.2d 1036 (2009) (same). Given the fundamental right at stake, it is incumbent upon our courts to make abundantly clear that they are not engaging in such improper comparisons. See In re Juvenile Appeal (Anonymous ), supra, 177 Conn. at 673, 420 A.2d 875 (quoting passage from United States Supreme Court decision that "forcefully recognized th[e] danger" of comparing advantages of child's natural parents with prospective adoptive parents).
**662Having concluded that the trial court's comparison was improper, I must consider whether this impropriety was harmless.2 E.g., In re Elvin G., 310 Conn. 485, 512-13, 78 A.3d 797 (2013) (applying harmless error analysis in termination of parental rights case), overruled in part on other grounds by In re Shane M., 318 Conn. 568, 587-88, 122 A.3d 1247 (2015). Even assuming, without deciding, that the petitioner, the Commissioner of Children and Families, would bear the burden of demonstrating harmlessness beyond a reasonable doubt; State v. Artis, 314 Conn. 131, 159, 101 A.3d 915 (2014) (state bore burden of demonstrating harmlessness beyond reasonable doubt when impropriety was of constitutional magnitude); see also In re Yasiel R., 317 Conn. 773, 782, 120 A.3d 1188 (2015) (termination of parental rights proceedings implicate constitutional rights); that standard clearly is satisfied in this case.
The trial court's decision is replete with facts establishing that the respondent failed to rehabilitate, untainted by any comparison to Paula M. The court **663found, among other things, that the respondent: (1) "is a volatile and sometimes violent individual"; (2) never adequately addressed "her communication skills so that she could engage in cooperative relationships with professionals who provide services to her and her children"; (3) "failed to acknowledge responsibility for the conditions leading to the children's removal" such that the services offered to her "have essentially been ineffective"; (4) *1162refused to communicate with her children's therapists; and (5) failed to acknowledge or appreciate the extent to which either domestic violence and substance abuse have been a significant source of trauma to her children or the significance of her children's behaviors, in and of themselves. Most significantly, the court found that the respondent "has none of the qualities the children have required to stabilize and to continue to heal from the traumas they experienced while in their parents' care." (Emphasis added.)
Thus, it is clear that, even without considering the favorable attributes of Paula M., the court necessarily would have concluded that the respondent "failed to achieve such degree of personal rehabilitation as would encourage the belief that within a reasonable time, considering the age and needs of [her children, she] could assume a responsible position in" their lives. General Statutes (Rev. to 2013) § 17a-112 (j)(3)(B) ; see also In re Etta H., 146 Conn.App. 751, 759, 78 A.3d 295 (2013) (although "the standard is not full rehabilitation, the parent must show more than any rehabilitation" [internal quotation marks omitted] ). I therefore respectfully concur in the judgment.
