All individuals possess a distinct combination of relative strengths and abilities. Those abilities that fall within the cognitive domain determine one’s intellectual ability or intelligence. Often it is necessary and helpful to obtain a measure of an individual’s intelligence. Such measures are often useful tools to help individuals decide appropriate post-secondary training  options. The most widespread test of intelligence that is used in North America is the Wechsler Intelligence Scale for Children-Forth Edition (WISC-IV) and the Wechsler Adult Intelligence Scale-Third Edition (WAIS-III). Each measures a wide variety of cognitive abilities and is used to determine an individual’s unique learning profile as well as overall intellectual ability.
