Intellectual Disability

An intellectual disability is defined as significantly below average general intellectual and adaptive functioning manifested during the developmental period, with significant delays in academic skills. Developmental period refers to birth to eighteen years of age.


The minimum evaluation for determining eligibility shall include all of the following:

  • A standardized individual test of intellectual functioning administered by a qualified professional.
  • A standardized assessment of adaptive behavior to include parental or guardian input.
  • An individually administered standardized test of academic or pre-academic achievement.
  • A social-developmental history which has been compiled directly from the parent, guardian, or primary caregiver.

Criteria for eligibility: A student with an intellectual disability is eligible for exceptional student education if all of the following are met:

  • The measured level of intellectual functioning is more than two standard deviations below the mean on an individually measured, standardized test of intellectual functioning.
  • The level of adaptive functioning is more than two standard deviations below the mean on the adaptive behavior composite or on two out of three domains on a standardized test of adaptive behavior. The adaptive behavior measure shall include parental or guardian input.
  • The level of academic or pre-academic performance on a standardized test is consistent with the performance expected of a student of comparable intellectual functioning.
  • The social/developmental history identifies the developmental, familial, medical/health, and environmental factors impacting student functioning and documents the student’s functional skills outside of the school environment.

Additional Information:

  • After a student qualifies for an Intellectual Disability (InD) with an IQ of 55 or higher and the first three year reevaluation occurs, the team must request a full reevaluation with an intellectual test, achievement test and adaptive behavior rating scales(parent and teacher) requested.
  • The student must meet eligibility criteria again on the first three year reevaluation.
