Overview
The Wechsler Abbreviated Scale of Intelligence – Second Edition (WASI-II; Wechsler, 2011) is an individually administered, norm-referenced, brief, reliable measure of cognitive ability for persons ages 6 through 90 years, 11 months old. Flexible administration offers the opportunity to include either two or four subtests, and results yield Verbal Comprehension Index (VCI; crystallized ability), Perceptual Reasoning Index (PRI; nonverbal fluid ability), and Full Scale IQ scores. The purposes of the WASI-II include screening for intellectual giftedness or disabilities; determining if in-depth assessment is needed; reassessing after a comprehensive evaluation; and estimating a range of Full Scale IQ scores. Subtests “mirror” content from the WISC-IV and WAIS-IV.
