Intelligence/ intellectual functioning testing (IQ test)

Intellectual functioning testing aims to evaluate an individual’s ability to think, solve problems, analyze situations, and understand social values, customs, and norms. Intelligence is sometimes referred to intelligence quotient (IQ), cognitive functioning, intellectual ability, aptitude, thinking skills and general ability. Two main forms of intelligence are included in most intelligence assessments:

(a) Verbal Intelligence – ability to comprehend and solve language-based problems
(b) Nonverbal Intelligence – ability to understand and solve visual and spatial problems.

Wechsler Adult Intelligence Scale (WAIS) is the most common individually administered IQ test for adults.

Intellectual assessment is also a method used by the clinical practitioner to measure a child’s intellectual capabilities in several specific domains. These domains include verbal comprehension, factual knowledge, abstract reasoning, visual-spatial abilities and short-term memory. Intellectual assessment is a good indication of a child’s academic potential. The results of an IQ test rank a child against a very large sample of children the same age. If a child scores in the top 5% for their age group it is reasonable to expect them to be performing within the top 5% academically. The Wechsler Intelligence Scale for Children (WISC) is the most common individually administered IQ tests for children.
