¶ 1 In this unemployment compensation benefits case, petitioner, A Child's Touch, seeks review of a final order of the Industrial Claim Appeals Office (Panel) holding that its former employee, claimant Robert L. Morris, was entitled to benefits because he was engaged in covered employment when A Child's Touch terminated his employment in September 2013. We conclude that A Child's Touch does not meet the statutory criteria for exemption from the Colorado Employment *992Security Act (CESA), §§ 8-70-101 to 8-84-108, C.R.S.2015, because it is neither "operated, supervised, controlled, or principally supported by a church or convention or association of churches" nor an "elementary or secondary school" within the meaning of section 8-70-140(1)(a), C.R.S.2015. We therefore affirm the Panel's decision.
I. Background
¶ 2 A Child's Touch is a state-licensed child care center providing infant and toddler day care, preschool, and kindergarten programs for children from six weeks to six years of age, and a summer camp for children ages six to twelve years.
¶ 3 Christian-themed iconography, prayers, and devotions are incorporated into its daily curriculum. Students recite the pledge of allegiance to both the United States flag and a Christian flag. Religious-themed activities are incorporated, including art projects depicting religious scenes, the reading of Bible stories, and religious-themed counting lessons. A Child's Touch maintains a seasonally-inspired "creation station" at which children can interact with models and images depicting Bible scenes such as Noah's Ark, Christ's Resurrection, and the Christmas Nativity. In addition, Christian holidays are celebrated through activities such as a "Happy Birthday Jesus" party during the Christmas season, the reenactment of the Easter story, and the baking of "resurrection biscuits." A Child's Touch also promotes its Christian-based education on its outdoor sign and Ten Commandments stone tablet. It joined the Association of Christian Schools International (ACSI) in 2013, and, a year later, in 2014, after claimant's termination, gained ACSI accreditation.
¶ 4 In addition to A Child's Touch being licensed as a child care center by the Department of Human Services, its kindergarten is licensed by the Colorado Department of Education, and children spend most of their days engaged in academic pursuits such as preparation for reading, writing, math, and science.
¶ 5 A Child's Touch was partially controlled by the Maranatha Christian Church, which had the authority to "sell" A Child's Touch. However, that relationship ended when the church ceased operations in 2011.1
¶ 6 A Child's Touch is run by a board of directors. Members of the board have included the founder of A Child's Touch, his wife and daughter, and an ordained minister who has not served as pastor of any particular church since before claimant's termination. In 2014, after claimant's termination, A Child's Touch added the pastor of Thrive Church to its board of directors.
¶ 7 Claimant served as a maintenance worker at A Child's Touch from approximately 1997 until his termination in September 2013. In September 2013, claimant took a medical leave for double hip replacement surgery. His position was eliminated during his absence. When he filed for unemployment compensation benefits, A Child's Touch challenged his request on the ground that he was not in covered employment and that it was exempt from unemployment compensation taxes under CESA because it is a religious organization. See § 8-70-140(1)(a).
¶ 8 After conducting two hearings and reviewing numerous exhibits, the hearing officer was persuaded that A Child's Touch operated primarily for religious purposes and was principally supported by a church or association of churches. See § 8-70-140(1)(a). The hearing officer denied claimant's claim for unemployment compensation benefits.
¶ 9 A divided Panel set aside the hearing officer's decision, holding that, although the evidence established that A Child's Touch operated primarily for religious purposes, the evidence did not support the hearing officer's finding that A Child's Touch is "principally supported" by an association of churches. Because this conclusion would disqualify A Child's Touch from the CESA exemption, the Panel went on to consider whether A Child's Touch qualified for the exemption on an alternative basis, namely as an elementary *993school that is operated primarily for religious purposes. The majority of the Panel then found that A Child's Touch was not an elementary school within the meaning of section 8-70-140(1)(a) either, and thus did not qualify for the unemployment compensation tax exemption.
II. Issues on Appeal
¶ 10 A Child's Touch contends that the Panel misinterpreted the evidence and the applicable statute. Specifically, it asserts that (1) it was "principally supported" by an association of churches during the period in question; and (2) the Panel misconstrued section 8-70-140(1)(a) by excluding facilities, such as A Child's Touch, which offer kindergarten but include no higher grades, from fitting within the meaning of "elementary school."
¶ 11 Claimant agrees with the outcome of the Panel's decision, but cross-appeals the Panel's determination that A Child's Touch operates primarily for religious purposes. He contends that because students at A Child's Touch spend the majority of their time pursuing nonreligious, secular academics, A Child's Touch's primary activity is education, not religion.
¶ 12 We conclude that A Child's Touch is neither principally supported by a church or association of churches nor an elementary school within the meaning of section 8-70-140(1)(a). Accordingly, we hold that the Panel correctly determined that A Child's Touch is not entitled to a religious exemption from unemployment compensation taxes under CESA.
III. Standard of Review
¶ 13 We are bound by the hearing officer's factual findings if they are supported by substantial evidence in the record. Goodwill Indus. v. Indus. Claim Appeals Office, 862 P.2d 1042, 1046 (Colo.App.1993).
¶ 14 However, we are not bound by the hearing officer's or Panel's determinations of ultimate facts. Samaritan Inst. v. Prince-Walker, 883 P.2d 3, 9 (Colo.1994). "Ultimate conclusions of fact ... are conclusions of law or mixed questions of law and fact that are based on evidentiary facts and determine the rights and liabilities of the parties.... [A]n ultimate conclusion of fact is as a general rule phrased in the language of the controlling statute or legal standard." Federico v. Brannan Sand & Gravel Co., 788 P.2d 1268, 1272 (Colo.1990).
¶ 15 Thus, while we are bound by any findings the hearing officer made concerning A Child's Touch's activities if those findings are substantially supported by evidence in the record, neither we nor the Panel is bound by the hearing officer's ultimate conclusions that A Child's Touch operates primarily for religious purposes or that A Child's Touch is principally supported by an association of churches. See Samaritan Inst., 883 P.2d at 9.
¶ 16 Moreover, we review the Panel's legal conclusions de novo. See Bell v. Indus. Claim Appeals Office, 93 P.3d 584, 586 (Colo.App.2004). In particular, we "review questions of statutory construction de novo." Mounkes v. Indus. Claim Appeals Office, 251 P.3d 485, 487 (Colo.App.2010).
IV. Section 8-70-140(1)(a)
¶ 17 The statute at issue, section 8-70-140(1)(a), states that for purposes of CESA:
¶ 18 "[E]mployment" does not include services performed:
(a) In the employ of a church or a convention or association of churches or in the employ of an organization that is operated primarily for religious purposes and that is operated, supervised, controlled, or principally supported by a church or convention or association of churches or in the employ of an elementary or secondary school that is operated primarily for religious purposes.
¶ 19 Accordingly, to qualify for the CESA exemption, A Child's Touch must be either:
(1) a church or a convention or association of churches,
(2) an organization that is operated primarily for religious purposes and that is operated, supervised, controlled, or principally supported by a church or convention or association of churches, or *994(3) an elementary or secondary school that is operated primarily for religious purposes.
¶ 20 A Child's Touch argues that it qualifies under both the second and third categories. We agree with the Panel and the hearing officer that A Child's Touch is operated primarily for religious purposes2 within the meaning of section 8-70-140(1)(a), which is a requirement for both the second and third categories. For A Child's Touch to qualify for the CESA exemption, we must also agree with it either (a) that it is principally supported by a church or convention or association of churches,3 or (b) that it is an elementary school.
A. Principally Supported by an Association of Churches
¶ 21 A Child's Touch contends that the Panel erroneously concluded that it is not "principally supported by [an] association of churches." It argues that the evidence established that it receives support from several churches, and that this support is sufficient to meet the statutory requirement. See § 8-70-140(1)(a). In particular, it cites to testimony that members of churches serve on its board, "offer prayer support, spiritual advice and guidance, provide referrals, and promote and market the school to their congregations."
¶ 22 Reviewing the record as a whole, we are not convinced that A Child's Touch was principally supported by an association of churches when claimant was discharged in September 2013.
¶ 23 To establish "principal" support, the entity seeking exemption from unemployment compensation taxes must establish that it " 'could not exist' without the churches' support, in other words, it is dependent upon that support. Such dependency constitutes 'principal' support for purposes of [the parallel Idaho act]." Nampa Christian Sch. Found., Inc. v. State, 110 Idaho 918, 719 P.2d 1178, 1184 (1986). A Child's Touch did not meet this burden.
¶ 24 The evidence presented showed only minimal association between A Child's Touch and any church during the critical period surrounding claimant's termination. See § 8-70-103(2), C.R.S.2015; § 8-73-102, C.R.S.2015 (claimant's unemployment compensation benefit is based on wages earned within the year and a half preceding his initial claim).
¶ 25 A Child's Touch did not establish that it required the support of any church to continue operating when it terminated claimant's employment. To the contrary, the evidence established that Maranatha Christian Church, which had asserted some level of control over A Child's Touch, ceased to exist several years before claimant's termination and was not supporting A Child's Touch at the time of claimant's termination. See Unity Christian Sch. of Fulton, Ill. v. Rowell, 379 Ill.Dec. 517, 6 N.E.3d 845, 852-53 (Ill.App.Ct.2014) (principal support exemption not established because the fact that the school was run out of the basement of a church when it started ninety-two years earlier failed "to demonstrate how the school is *995currently supported principally by the churches" and evidence instead showed school was presently a separately incorporated entity in a separate building with a constitution that states it is not affiliated with any ecclesiastical body).
¶ 26 And while A Child's Touch secured ACSI accreditation, that did not happen until after claimant was terminated. Moreover, the evidence showed that although the former pastor of the defunct Maranatha church was once on A Child's Touch's board, he was no longer serving as a pastor when A Child's Touch terminated claimant. Further, although the hearing officer noted that A Child's Touch's "current board chairman is a [minister] with" a local church, the composition of A Child's Touch's board at the time of the hearing was not at issue in May and September of 2014. Rather, the critical period was at the time of claimant's termination in September 2013. Finally, the evidence established that the pastor on A Child's Touch's board at the time of the hearing did not join the board until 2014, long after claimant's departure. In short, a snapshot of the period in which claimant was terminated does not establish that A Child's Touch was principally supported by a church or association of churches. See Nampa Christian Sch., 719 P.2d at 1184.
¶ 27 The other factual finding cited by the hearing officer likewise provides only tenuous support for his conclusion that A Child's Touch was principally supported by an association of churches. The hearing officer found that various churches "promote" A Child's Touch "to their individual members," and that A Child's Touch "relies on families being referred by the various churches in the area to keep operating." But the testimony from which the hearing officer drew this finding did not clearly establish this. The testimony instead confirmed that churches refer some families to A Child's Touch, but never established that A Child's Touch could not exist without those referrals.
¶ 28 In the absence of evidence demonstrating that its operations at the time of claimant's termination depended on such support, A Child's Touch failed to show that the support of any church or churches was "necessary for [its] continued operation." Id. The level of support A Child's Touch described during the period in question resembles the "moral support" Nampa Christian Schools rejected as insufficient. See id. The key is the quality of support during the period in which claimant was terminated, September 2013. Here, although a church supported A Child's Touch prior to claimant's termination and the current board contains local pastors, we conclude that A Child's Touch was not principally supported during the time period in which claimant was actually terminated.
¶ 29 Therefore, we agree with the majority of the Panel that A Child's Touch failed to establish that it was "principally supported by a church or convention or association of churches." See § 8-70-140(1)(a).
¶ 30 Because we have concluded that A Child's Touch is not an exempt organization under the second category described in section 8-70-140(1)(a), we are required to consider whether A Child's Touch nonetheless qualifies for the religious exemption from CESA by falling into the third category: an elementary or secondary school that is operated primarily for religious purposes.
B. Elementary School
¶ 31 We also disagree with A Child's Touch's contention that the Panel erred by failing to find that it is an elementary school within the meaning of CESA. § 8-70-140(1)(a). Specifically, we reject A Child's Touch's assertion that the inclusion of kindergarten in its curriculum necessarily makes it an "elementary school" within the meaning of section 8-70-140(1)(a).
¶ 32 CESA neither defines "elementary school" nor clearly articulates the legislature's intended scope of the term. Without a statutory definition, dictionary definitions can guide us. "When a statute does not define its terms but the words used are terms of common usage, we may refer to dictionary definitions to determine the plain and ordinary meaning of those words." Gagne v. Gagne, 2014 COA 127, ¶ 29, 338 P.3d 1152 (quoting Bachelor Gulch Operating Co. v. Bd. of Cty. Comm'rs , 2013 COA 46, ¶ 25, 316 P.3d 43 ). Additionally, the context in which an undefined term is used "may provide *996guidance as to legislative intent and the term's proper meaning." Fogg v. Macaluso , 892 P.2d 271, 274 (Colo.1995).
¶ 33 As pertinent here, Webster's Third New International Dictionary 735 (2002) defines "elementary school" as "A school in which elementary subjects (as reading, writing, spelling, and arithmetic) are taught to children from about six to about twelve years of age which in the U.S. covers the first six or eight grades." In our view, this definition is not broad enough to include a child care facility which offers kindergarten within the ordinary meaning of "elementary school."
¶ 34 We find persuasive the statutory definition of a "child care center" in the Human Services Code. There, it explains that a kindergarten is a child care center unless the kindergarten is "maintained in connection with a public, private, or parochial elementary school system of at least six grades or operated as a component of a school district's preschool program...." § 26-6-102(1.5), C.R.S. 2015.4 A Child's Touch is indisputably not maintained in connection with a public, private, or parochial elementary school system of at least six grades nor operated as a component of a school district's preschool program. This provision, thus, supports the conclusion that the presence of a kindergarten class does not convert a child care facility into an "elementary school" for the purpose of section 8-70-140(1)(a).
¶ 35 Conversely, we are not persuaded by the statutes A Child's Touch relies upon to support its proposed broad definition of "elementary school." It points to Title 22, which defines "school age" as "any age over five and under twenty-one years." § 22-1-115, C.R.S.2015. Under the School Attendance Law of 1963, Title 22 provides that "every child who has attained the age of six years on or before August 1 of each year and is under the age of seventeen years ... shall attend public school." § 22-33-104(1)(a), C.R.S. 2015. However, neither of these statutes defines "elementary school" and neither specifies that a child care facility which includes a kindergarten constitutes an elementary school.
¶ 36 Other jurisdictions examining the meaning of "elementary school" have concluded that a facility that offers preschool and kindergarten, but no grades beyond kindergarten, does not qualify as an "elementary school." For example, in Commonwealth v. Burke, 44 Mass.App.Ct. 76, 687 N.E.2d 1279 (1997), the Appeals Court of Massachusetts reversed a defendant's conviction for drug offenses within a school zone because the school in question, a preschool, did not qualify as an "elementary school" under the statute. Id. at 1282. Citing the definition contained in Webster's Third New International Dictionary, the court held that "a kindergarten, together with a preschool, is not an elementary school." Id. at 1281.
¶ 37 The District Court of Appeal of Florida reached the same conclusion when it determined that a "kindergarten/preschool" is not an elementary school within the meaning of Florida's penal code. The court therefore affirmed the dismissal of charges against a defendant for purchasing illicit drugs "within 1,000 feet of the real property comprising a public or private elementary, middle, or secondary school." State v. Roland, 577 So.2d 680, 681 (Fla.Dist.Ct.App.1991).
¶ 38 The Supreme Court of New Jersey followed this reasoning in vacating the conviction of a defendant charged with distributing drugs on the property of "any elementary or secondary school," reasoning that the ten-student kindergarten class there did not "transform a day care center into an elementary school" for purposes of that statute. State v. Shelley, 205 N.J. 320, 15 A.3d 818, 820, 824 (2011). The court recognized that while some definitions "lead to a conclusion that an elementary school generally includes the first six to eight grades and may include a kindergarten program as an introduction to formal education, ... none definitively establish[es] whether a kindergarten class, standing unconnected to other elementary grades, *997constitutes an 'elementary school.' " Id. at 820-21. And, further emphasizing the similarities with this case, the court observed that without higher grades, "the essential character of [the facility] is a day care center." Id. at 824.
¶ 39 We are persuaded by the reasoning of Shelley, Burke, and Roland . Because section 8-70-140(1)(a) creates an exemption for services performed "in the employ of an elementary ... school ...," it is appropriate in this context to characterize the facility as a whole. See Fogg, 892 P.2d at 274. When so analyzing A Child's Touch, it is apparent that it is more akin to a child care center than an elementary school.5
¶ 40 We need not elucidate a comprehensive definition of "elementary school" to conclude that A Child's Touch does not fall within the "elementary school" exception of section 8-70-140(1)(a). Thus, unlike the Panel majority, we do not conclude that an elementary school necessarily consists of first through sixth or first through eighth grades, or that kindergarten students are not elementary school students. Instead, it is sufficient in this case to conclude that an entire child care facility is not properly characterized as an "elementary school" for unemployment compensation tax purposes simply because it happens to provide a kindergarten program for its oldest charges.
¶ 41 We thus hold that a child care facility such as A Child's Touch, which offers day care, preschool, and kindergarten, but does not teach any higher grades, is not an "elementary school" for purposes of a religious exemption from unemployment compensation taxes under section 8-70-140(1)(a).
V. Conclusion
¶ 42 We therefore conclude that the majority of the Panel correctly held that A Child's Touch did not meet the criteria for a religious exemption under section 8-70-140(1)(a).
¶ 43 Accordingly, the Panel's order is affirmed, and the case is remanded to the Division of Unemployment Insurance to determine claimant's entitlement to and eligibility for unemployment compensation benefits.
