Weschler Abbreviated Scale of Intelligence Record Forms (WASI-II)

The Weschler Abbreviated Scale of Intelligence, Second Edition (WASI-II) is an instrument designed for the assessment of intelligence and cognitive functioning in individuals aged 6 to 90 years. It helps psychologists, clinicians, and researchers rapidly screen for intellectual disabilities or intellectual giftedness. This tool provides professional teams with a framework that facilitates efficient intellectual screening and reassessment and allows them to tailor further comprehensive evaluations and support plans based on reliable IQ estimates.

Benefits:

• Quick screening: Determines if an in-depth intellectual assessment is necessary.

• Reassessment utility: Useful for follow-up assessments after comprehensive evaluations.

• Accurate IQ estimation: Estimates a range of Full Scale IQ (FSIQ) scores from comprehensive batteries.

• Versatile use: Assesses cognitive functioning for psychiatric, vocational, rehabilitation, and research purposes.

• Ability-achievement comparison: Supports analysis of academic strengths and needs via discrepancy analysis.

Key Features:

• Updated subtests: Improved Vocabulary, Similarities, Block Design, and Matrix Reasoning tasks with streamlined instructions.

• Flexible administration: Two-subtest form takes approximately 15 minutes; four-subtest form takes about 30 minutes.

• Alignment with Wechsler batteries: Revised items closely parallel WISC-IV and WAIS-IV counterparts.

• Reduced additional testing: Only six more subtests needed to derive all WISC-IV or WAIS-IV composite scores.

• Robust standardization: Normed on a nationally representative sample of ~2,300 individuals aged 6 to 90 (2010–2011).
