The Wechsler tests are some of the most common IQ tests and include the Wechsler Preschool and Primary Scale of Intelligence, the Wechsler Intelligence Scale for Children, and the Wechsler Adult Intelligence Scale (WAIS-IV).
What is the WAIS-IV?
The Wechsler Adult Intelligence Scale-Fourth Edition is a standardized test of intelligence used to measure a range of cognitive abilities. The test measures a person’s ability to think abstractly, solve problems, deal with new situations, and profit from experience. The WAIS-IV is used for individuals ages 16 through 90.
WAIS-IV summary score is the Full Scale IQ (FSIQ). The FSIQ is derived from a combination of ten subtest scores and is considered the most representative estimate of overall intellectual functioning. The Full Scale IQ is made up of four index scores including the Verbal Comprehension Index (VCI), the Perceptual Reasoning Index (PRI), the Working Memory Index (WMI), and the Processing Speed Index (PSI). Scores between 90 and 110 are considered in the Average range for each of these Indexes and the Full Scale IQ.
What is the WAIS-IV used for?
The WAIS-IV is commonly used by psychologists to help identify teens and adults with developmental disabilities, learning disabilities, or cognitive problems. The WAIS-IV can help individuals qualify for any needed special services including recommending appropriate interventions for cognitive difficulties.
