WASI-II gives psychologists, clinicians, and researchers a fast and reliable measure of intelligence when screening for intellectual disabilities or intellectual giftedness. WASI-II is also useful for reassessing individuals following a comprehensive evaluation.
- Screen to determine if in-depth intellectual assessment is needed.
- Reassess after a comprehensive evaluation.
- Estimate a range of FSIQ scores on comprehensive batteries.
- Assesses cognitive functioning of individuals referred for psychiatric evaluations.
- Measure IQ scores for vocational, rehabilitation, or research purposes.
- Compare results to the Wechsler Family Fundamentals: Academic Skills to determine a student’s academic strengths and needs based on an ability-achievement discrepancy analysis.
The WASI-II builds on the strength of the WASI, providing updated versions of the WASI Vocabulary, Similarities, Block Design and Matrix Reasoning subtests. WASI-II also offers flexible administration options and strengthened connections with the WISC-IV and WAIS-IV.
- Subtests are updated to provide a variety of improvements including shortened and streamlined instructions.
- Four-subtest form can be administered in just 30 minutes; two-subtest form in about 15 minutes.
- WASI-II subtests and items are revised to more closely parallel their counterparts in the WISC-IV and WAIS-IV.
- Only six more subtests (rather than ten) need administering from the comprehensive measure to derive all WISC-IV or WAIS-IV composite scores.
- Standardization of the WASI-II was conducted from January 2010 to May 2011 on a nationally representative sample of approximately 2,300 individuals aged 6–90.
