OPINION BY
Lycoming-Clinton County Mental Health/Mental Retardation Program (the County Agency) petitions for review of the September 28, 2004, order of the Department of Public Welfare (DPW) affirming the Administrative Law Judge’s (ALJ) decision to direct the County Agency to provide mental retardation (MR) services to T.T. We also affirm.
In April 2002, T.T.’s parents filed an application with the County Agency requesting MR services on behalf of their nineteen-year-old son. After reviewing the evaluations of T.T. performed by Richard E. Dowell, Jr., Ph.D., which showed that T.T. had a full scale IQ score of 103, the County Agency concluded that the documentation collected was not sufficient to determine whether T.T. was eligible for MR services. The County Agency received an addendum from T.T.’s parents in July 2002 detailing the processing discrepancy between T.T.’s higher level reasoning and real world social interaction (lower level executive functioning). Subsequently, the County Agency notified T.T.’s parents that because T.T.’s IQ score of 103 *383was too high, he was not eligible for MR services. (Findings of Fact, Nos. 1-5.)
T.T.’s counsel requested that the County Agency reassess T.T.’s eligibility for MR services based on a subsequent evaluation performed by Dr. Dowell, and, in response, the County Agency recommended that T.T.’s parents obtain an independent opinion regarding T.T.’s functioning ability. After an evaluation performed by Dawn Hoffman, a licensed psychologist, showed that T.T. had a full scale IQ score of 89, the County Agency again notified T.T.’s parents that T.T. was not eligible for MR services because his full scale IQ score of 89 was too high. Counsel for T.T. then filed an administrative appeal to DPW requesting that T.T. be determined eligible for MR services. (Findings of Fact, Nos. 6-10.)
At the administrative hearing on February 10, 2004, both Dr. Dowell and Hoffman testified that T.T. has Prader-Willi Syndrome, Attention Deficit Disorder, a Learning Disorder Not Otherwise Specified, and Oppositional Defiant Disorder. (Findings of Fact, No. 11.)
In addition, Hoffman testified before the ALJ that most patients diagnosed with Prader-Willi Syndrome also have been diagnosed as being moderately mentally retarded. She also stated that T.T.’s adaptive behavioral skills are severely impaired and are clearly more consistent with those of an individual with moderate to severe mental retardation as opposed to those of an average nineteen-year-old. Nevertheless, Hoffman testified that she did not diagnose T.T. as being mentally retarded because his full scale IQ score was 89. (Findings of Fact, Nos. 12-15.)
Testifying on behalf of T.T., Dr. Dowell stated that, although T.T.’s full scale IQ score of 103 fell within the average range, there was a high level of variability between T.T.’s concrete, factual knowledge and his fluid/flexible mental processing test scores. Dr. Dowell testified that T.T.’s actual “real world” cognitive performance, or higher level executive/reasoning functions, fell within the borderline to impaired range, with a score of 73. Dr. Dowell also stated that T.T.’s score of 45 on the Vineland Adaptive Behavioral Scales fell within the impaired range with overall level of “real world” adaptation falling within the moderate range of MR. Dr. Dowell diagnosed T.T. with functional moderate mental retardation, and he opined that T.T. had the functional ability of a seven year old. (Findings of Fact, Nos. 16-21.)
The ALJ rejected Hoffman’s opinion that T.T. could not be diagnosed with MR because of his IQ score. Instead, the ALJ accepted Dr. Dowell’s opinion that, even with an IQ of 103, T.T. should be diagnosed as functionally moderately mentally retarded based on criteria unrelated to the full scale IQ score as set forth in 55 Pa. Code § 4210.101a. (Findings of Fact, No. 24.)
The County Agency filed a motion for reconsideration with DPW, and, by order dated September 28, 2004, DPW upheld the decision of the ALJ requiring the County Agency to provide MR services to T.T. The County Agency now petitions this court for review.1
The County Agency argues that DPW’s use of criteria other than IQ was unwarranted in T.T.’s case where his 103 IQ rendered him automatically ineligible for MR support services based on criteria es*384tablished in 55 Pa.Code § 4210.101a(a).2 The County Agency also argues that the ALJ erred in crediting Dr. Dowell’s opinion, which used factors other than IQ score to diagnose T.T. with MR. In support of these arguments, the County Agency relies on the eligibility criteria for MR services, which provide in relevant part as follows:
§ 4210.101a. Clarification of eligibility determinations — statement of policy.
(a) The essential feature of mental retardation is significantly subaverage general intellectual functioning that is accompanied by significant limitations in adaptive functioning ....
(1) [Significantly subaverage general intellectual functioning shall be determined by a standardized, individually administered, intelligence test in which the overall full scale IQ score of the test and of the verbal/performance scale IQ scores are at least two standard deviations below the mean taking into consideration the standard of error measurement for the test. The full scale IQ shall be determined by the verbal and performance IQ scores {See Appendix A — DSMIV).
(2) Diagnosis of mental retardation is made by using the IQ score, adaptive functioning scores and clinical judgment when necessary. Clinical judgment is defined as reviewing the person’s test scores, social and medical history, overall functional abilities, and any related factors to make an eligibility determination. Clinical judgment is used when test results alone cannot clearly determine eligibility. .... In cases when individuals display widely disparate skills or achieve an IQ score close to 70, clinical judgment should be exercised to determine eligibility for mental retardation services.
Appendix A
Impairments in adaptive functioning, rather than a low IQ, are usually the presenting symptoms in individuals with Mental Retardation. Adaptive functioning refers to how effectively individuals cope with common life demands and how well they meet the standards of personal independence expected of someone in their particular *385age group, socio-cultural background, and community setting....
55 Pa.Code § 4210.101a (emphasis added) (footnote omitted).
Based on its interpretation of the language of subsection (a) of the policy, the County Agency maintains that T.T. cannot be diagnosed as mentally retarded because eligibility for MR services requires an IQ below 70. Further, the County Agency asserts that, under subsection (a)(2) of the policy, MR can only be diagnosed if the full scale IQ is 70 or slightly higher and the low IQ is accompanied by limited adaptive functioning. The County Agency reasons that because T.T.’s IQ scores do not provide the initial and vital criteria for MR, consideration of adaptive functioning scores or clinical judgment is inappropriate.3 Because the County Agency’s argument fails to consider the entire policy,4 we disagree with this interpretation of 55 Pa. Code § 4210.101a.
Section (a)(2) of the policy expressly requires that diagnosis of MR must be based on IQ score, adaptive functioning scores and clinical judgment when necessary. 55 Pa.Code § 4210.101a(a)(2). Clinical judgment is necessary when, as here, an individual displays widely disparate skills. Id. Additionally, Appendix A of the policy explains that, when there is a marked discrepancy across an individual’s performance and verbal scores, a mathematically derived full scale IQ score can be misleading. 55 Pa.Code § 4210.101a, Appendix A. Indeed, Appendix A provides that “impairments in adaptive functioning, rather than a low IQ, are usually the presenting symptoms in individuals with Mental Retardation.” Id.
Here, the ALJ determined that T.T.’s disparate skill levels, as evidenced by widely varying test scores, and T.T.’s low scores in adaptive functioning, made the use of clinical judgment necessary to diagnose T.T. (ALJ’s op. at 10.) Considering the policy in its entirety, we conclude that DPW did not err in allowing consideration of factors other than IQ to determine T.T.’s eligibility for MR services.5 In fact, the policy warns of the misleading nature of IQ scores under certain circumstances. *386The ALJ determined that this was such a case, and the credible testimony supports this determination.
Accordingly, we affirm.
ORDER
AND NOW, this 7th day of October, 2005, the order of the Pennsylvania Department of Public Welfare, dated September 28, 2004, is hereby affirmed.
