1. (1)

   1. (A) “Intellectual disability (ID)” is defined by the American Association on Intellectual and Developmental Disabilities as referring to substantial limitations in present functioning, characterized by subaverage intellectual functioning existing concurrently with related limitations in two (2) or more applicable adaptive skill areas.

   2. (B) The adaptive skill areas mentioned in the definition are:

      1. (i) Communication;
      2. (ii) Self-care;
      3. (iii) Home living;
      4. (iv) Social skills;
      5. (v) Community use;
      6. (vi) Self-direction;
      7. (vii) Health and safety;
      8. (viii) Functional academics;
      9. (ix) Leisure; and
      10. (x) Work.
   3. (C) An intellectual disability manifests before age eighteen (18).

2. (2)

   1. (A) In making a diagnosis of an intellectual disability, the American Association on Intellectual and Developmental Disabilities suggests that the condition exists if:

      1. (i) The person's intellectual functioning level is below IQ 70–75;
      2. (ii) The onset is age eighteen (18) or below; and
      3. (iii) There are significant disabilities in two (2) or more adaptive skill areas.
   2. (B) In interpreting evaluation data, the committee must consider the effects of cultural and linguistic diversity on communication and behavior.
   3. (C) The existence of limitations in adaptive skills should be reflective of the context of community environments typical of the student's age peers.

3. (3)

   1. (A) To obtain a comprehensive picture of the student's abilities, all assessment information gathered must be integrated.
   2. (B) The information derived from assessment of the student's functioning levels in usual or natural environments is of primary importance to the development of an appropriate educational program.
   3. (C) The assessments conducted for programming can identify more specifically the student's areas of need than can other measures used to establish eligibility.

(g) Programming considerations.

1. (1)

   1. (A) In developing an IEP for the student with an intellectual disability, it is important that a positive educational approach be taken that stresses needed supports for the student to function in particular environments/situations.
   2. (B) The overall focus is to help the student develop the skills needed to function as independently as possible in natural environments.

2. (2)

   1. (A) It is often necessary and appropriate to consider a functional approach to academic instruction to facilitate development of the skills that are required for independence in daily living.

   2. (B) Such skills are required for:

      1. (i) Personal care;
      2. (ii) Independent daily living;
      3. (iii) Travel; and
      4. (iv) Successful competitive employment.
   3. (C) An activity-driven, skill-supported curriculum should serve as the foundation for individualized instruction.
   4. (D) Programs should be based on a team approach with skills and knowledge shared across professionals and settings.
   5. (E) When related services are a necessary part of the program for a student, those services should be integrated into the total daily program as much as possible.
   6. (F) Skills should be taught in the context or contexts and environment or environments in which the student is expected to perform them, especially since these students often have difficulty in generalizing skills to other settings.

   7. (G) Thus, instruction in communication and social skills development should be:

      1. (i) Incorporated into natural, functional routines and settings; and
      2. (ii) Integrated with other instructional content.

3. (3)

   1. (A) These students may need adaptations, modifications, and/or accommodations in order to receive their educational program in the least restrictive setting appropriate to their needs.
   2. (B) The program design should take into account the student's need for a structured learning environment.

   3. (C) A behavior management plan may be a necessary part of the IEP to address:

      1. (i) Appropriate behaviors to be taught or increased;
      2. (ii) Behaviors to be decreased; and
      3. (iii) Interventions to be used with any disruptive and/or noncompliant behavior.
