Wechsler Abbreviated Scale of Intelligence – Second Edition (WASI-II)

The Wechsler Abbreviated Scale of Intelligence – Second Edition (WASI-II; Wechsler, 2011) is an individually administered, brief, reliable measure of cognitive ability for clinical, educational, and research settings.

Overview

Flexible administration offers the opportunity to include either two or four subtests designed to be used with individuals aged 6 to 90. The purposes of the WASI-II include screening for intellectual giftedness or disabilities; determining if in-depth assessment is needed; reassessing; and estimating Full Scale IQ scores. Subtests include Vocabulary, Block Design, Similarities, and Matrix Reasoning, and these subtests “mirror” content from the WISC-IV and WAIS-IV. The four-subtest form yields three scores: FSIQ, general cognitive ability; VSI, crystallized abilities; and PIQ, nonverbal fluid abilities and visuomotor/coordination. The two-subtest form yields a FSIQ-2 score, which is an estimate of general cognitive ability.
