Wechsler Adult Intelligence Scale – Fourth Edition (WAIS-IV)

The WAIS-IV is the most commonly used test of intelligence for persons aged 16 through 75 years and may be the intelligence test chosen if your child is a teenager above the age of 15. The sub-tests on the WAIS-IV are generally “adult” versions of the sub-tests on the WISC-IV and V.

The excellent reliability and well-validated WAIS scales, as well as vast improvements in the structure, content, procedure, and clinical utility, make extraction of more meaningful information more readily available; however, examiner precision and accuracy are required for proper administration and scoring. The many short forms of the WAIS-III are also very useful when there are time or physical constraints; however, they are only recommended as a rough estimate or screening instrument for future assessment.
