What is Intelligence Testing?
Intelligence testing is a psychological assessment conducted to measure a person’s cognitive abilities and intellectual functioning It’s used to measure the individual’s mental ability in comparison to their peers. Intelligence testing embraces a variety of instruments and tests, including self-report scales, pencil and paper tests, and computer-based tests.
Intelligence testing has been used since the early 1900s, and the most widely used IQ test is the Wechsler Adult Intelligence Scale, in its fourth edition. IQ testing is based on the concept of intelligence as a global mental capacity, and it gauges the individual’s ability to solve abstract problems, reason logically, and learn from experience. IQ tests measure both verbal and non-verbal abilities in order to give an indication of the individual’s mental capacity.
Intelligence testing is used for a variety of purposes, such as assessing graduate school entry, determining career paths, assessing mental retardation and learning disabilities, and for identifying individuals who may need special education services. Intelligence testing is also used by employers to identify potential employees and by the military to assess candidates for officer training.
Despite the numerous advantages of intelligence testing, it has its limitations. For example, it does not necessarily measure skills that are important for life outside of the academic setting. Intelligence tests do not assess creativity, empathy, artistic ability, or other skills that may be just as important in many situations.
Five Examples of Intelligence Tests
1. Wechsler Adult Intelligence Scale (WAIS)
The most widely used IQ test, the WAIS evaluates various cognitive abilities, such as verbal comprehension, perceptual reasoning, working memory, and processing speed. It has been revised over the years, and the latest version, WAIS-IV, addresses the areas of short-term memory, visual-spatial processing, and quantitative reasoning.
2. Raven’s Progressive Matrices

3. Kaufman Assessment Battery for Children
