Intellectual disability


If a child is suspected of having an intellectual disability, the following evaluation must be conducted:


Intelligence test. An individually administered standardized intelligence test meeting the reliability and validity standards of the American Psychological Association and administered by a licensed school psychologist, a psychologist licensed by the State Board of Psychological Examiners, or other individual assigned by a school district who has the training and experience to administer and interpret individually administered intelligence tests;


Adaptive behavior scale. The administration of a valid adaptive behavior scale;


Medical or health assessment statement. A medical statement or a health assessment statement indicating whether there are any sensory or physical factors that may be affecting the child’s educational performance;


Developmental history. A developmental history of the child;




Any additional assessments necessary to determine the impact of the suspected disability:


On the child’s educational performance for a school-age child; or


On the child’s developmental progress for a preschool child; and


Any additional evaluations or assessments necessary to identify the child’s educational needs.


To be eligible as a child with an intellectual disability, the child must meet all of the following minimum criteria:


The child’s intelligence test score is 2 or more standard deviations below the mean;


The child has deficits in adaptive behavior coexistent with the child’s impairment in intellectual functioning;


The child’s developmental level or educational achievement is significantly below age or grade norms; and


The child’s developmental or educational problems are not primarily the result of sensory disabilities or other physical factors.


For a child to be eligible for special education services as a child with an intellectual disability, the eligibility team must also determine that:


The child’s disability has an adverse impact on the child’s educational performance; and


The child needs special education services as a result of the disability.
