Intellectual Disability Assessment

Intellectual Disability Assessment

The primary reason the majority of individuals undergo private testing for an Intellectual Disability (ID) is that this diagnosis will entitle the individual to services that he/she will need to assist with everyday living, such as employment, household management, and residential supports. In order to obtain these services the diagnosis of an Intellectual Disability must be confirmed via formalized testing conducted by a Licensed Psychologist.

In order to obtain the diagnosis of an Intellectual Disability, there are three (3) criteria that must be met:

  1. A Full Scale IQ of 70 or below must be obtained.
  2. There must be deficits evident in Adaptive Functioning
  3. The onset of the disability must be present prior to the age of 18 years old

Intellectual Disability Diagnosis Process

The goal of New Day Psychological Services, with regard to the diagnosis of an ID, is to assure that the evaluation conducted meets the County/State/Federal requirements allowing the individual with the ID to obtain entitled services.

First, a clinical interview is conducted. This process is used to obtain background information in a variety of areas to gain a comprehensive understanding of the individual’s functioning. This includes family history, developmental history, medical history, educational history, vocational history, and social history.

Second, an IQ test is administered. The choice is instrument is based on the person’s age as well as their verbal versus non-verbal status. At New Day, we have the ability to test individuals of all ages.

Third, an Adaptive Behavior Scale is completed. This is a questionnaire completed by a person who knows the individual very well. The purpose of this scale is to gain information regarding the individual’s adaptive abilities and to compare these to other persons in their same age group to determine how such skills compare and thus determine if deficits are present.

In some cases all three of these steps can be conducted in one appointment. In some cases, insurance companies may require that testing services be preauthorized. In these situations, two appointments will be necessary. The entire process typically takes between 2-4 hours depending on the individual.

Once the process is completed a written report (Diagnostic Intellectual Evaluation) will be completed. This report will be written in the language necessary to meet County/State/Federal requirements for the diagnosis of an Intellectual Disability. All testing for ID Determination is completed by Dr. Carey. He is well experienced in conducting these assessments and providing the necessary written documentation. He is well known by Lancaster County Behavioral Health & Developmental Services and his reports are respected by that agency.  As needed, he will also guide individuals and their families through the process of accessing services at the local County level.

When to be Tested

Testing for an Intellectual Disability can be conducted with children as well as adults. It is recommended that testing for purposes of entitled services not occur until the child is at least the age of 6-years-old as IQ scores obtained prior to this age are not predictive of future functioning. IQ testing and testing for developmental delays may occur prior to the age of 6 years in order to determine the extent of delays as well as to guide treatment that may be necessary within the particular age level as well as assist with eligibility for Early Intervention services.

Other uses of Intellectual Assessment

Secondary Diagnosis of Autism

In some cases, if Dr. Carey completes an Autism assessment and has a suspicion that there also may be an ID present he may recommend that an ID determination be completed as well.


In some cases testing of intellectual functioning can be helpful if there are behavioral issues present such as difficulties with attention and focus.

Learning Issues

If a person is having difficulties with learning, testing of intellectual functioning is a first step in understanding why these issues are present.
