The Wechsler Abbreviated Scale of Intelligence, Second Edition (WASI-II; Wechsler, 2011) is a brief intelligence test designed for individuals aged 6 through 90 years. It is a revision of the Wechsler Abbreviated Scale of Intelligence (WASI; Wechsler, 1999). During revision, there were three goals: enhancing the link between the Wechsler Intelligence Scale for Children, Fourth Edition (WISC-IV; Wechsler, 2003) and the Wechsler Adult Intelligence Scale, Fourth Edition (WAIS-IV; Wechsler, 2008a), increasing user-friendliness, and improving psychometric properties. Items from the WASI were dropped, modified, or retained after comparing them to items and scoring criteria on the WISC-IV and WAIS-IV. Furthermore, administration rules (e.g., reversal and discontinue rules) were modified in order to increase the consistency with other Wechsler instruments. Norms were updated, subtest floors and ceilings were extended, and reliability and validity evidence was generated.
