The Weschler Adult Intelligence Scale-III (WAIS-III) is the most widely used and well known adult intelligence test. A new version of the WAIS-III was published late in 1997, creating a need for a quick and easy guide on administering, and interpreting and reporting on the updated test. The Essentials of WAIS-III Assessment is the first and only book to provide mental health professionals and students with interpretive and administrative guides to the WAIS-III.
