Cognitive/Intellectual Disability (C/ID)

Cognitive/Intellectual Disability (C/ID) & Division of Developmental Disabilities (DDD)

In order for an individual to qualify for the Division of Developmental Disabilities (DDD) benefits, one must have 1) a qualifying diagnosis (such as Cognitive/Intellectual Disability (C/ID) and 2) at least three of several substantial functional limitations (SFLs) in the areas of self-care, receptive and expressive language, learning, mobility, self-direction, capacity for individual living, and economic self-sufficiency.  This document describes the requirements for DDD eligibility in detail. 

Dr. Andersen is able to evaluate for and diagnosis (or rule out the presence of an Intellectual Disability).  An Intellectual Disability is one has significant cognitive deficits (i.e., IQ below the 2nd percentile) and significant deficits in adaptive behavior.  It is important to note that not all individuals with an Intellectual Disability (C/ID) will qualify for DDD benefits.  Rather, one must also be able to document at least 3 SFLs.  Dr. Andersen will be able to speak to many of the aforementioned adaptive skills; however, he will not likely have all of the documentation that DDD requires for administrative review (i.e., Individual Support Plans (ISPs), habilitation reports, progress notes, SLP evaluations and notes, OT evaluations and notes, etc.).  But the more documentation you can provide Dr. Andersen the better he will be able to integrate that information in his evaluation.

What Do You Receive with a Cognitive/Intellectual Disability Evaluation?


  • Interview with the parent(s)/guardian(s) (~30 minutes)
  • IQ test with the client (~60 minutes including establishing rapport and interviewing the individual)
  • Receptive and Expressive Communication testing (~30 minutes)
  • Adaptive testing (questionnaires completed by the parent[s]/guardian[s])
    • Self-care, receptive and expressive language, learning, mobility, self-direction, capacity for independent living, economic self-sufficiency


  • Verbal Feedback (~30 minutes)
  • Written Report (~5 to 10 pages) with diagnostic impressions and practical recommendations

This evaluation is typically conducted over two sessions.  The first session is for the initial interview and direct face-to-face evaluation with your child. The second session is to provide you with verbal feedback with practical recommendations, at which time you will receive a written report.
