Intellectual functioning refers to an individual’s general mental (or cognitive) capacity, which includes problem solving, reasoning, memory, and leaning.

Most people have average intelligence.

  • An intellectual disability is present when low IQ scares are coupled with deficits in adaptive behavior, or everyday life skills.
  • Intellectual giftedness is present when IQ scares fall in the top 2 percent of population.
    *Some use the range of 2 to 5 percent.

How Intellectual Functioning is Assessed:

Intellectual functioning is commonly assessed through an IQ test. Some tests are entirely nonverbal, meaning that the individual does not need to use or understand spoken language. This type of measure is appropriate when assessing children who do not communicate verbally, are English language learners, or come from a background where language concepts may influence scores.

Components of a Comprehensive Evaluation Include:

  • Developmental History
  • Cognitive Assessment/s
  • Adaptive Assessment
  • Observation in Natural Setting
