Wechsler Abbreviated Scale of Intelligence®—Second Edition

The Wechsler Abbreviated Scale of Intelligence®—Second Edition (WASI®–II), a revision of the WASI®, provides a brief, reliable measure of cognitive ability for use in clinical, educational, and research settings. This revision maintains the format and structure of the WASI while offering new content and improvements to provide greater clinical utility and efficiency.

The WASI–II builds on the strength of the WASI by providing updated versions of the WASI Vocabulary, Similarities, Block Design and Matrix Reasoning subtests, flexible administration options (i.e., four- or two-subtest versions), and strengthened connections with the WISC®–IV and WAIS®–IV.

Psychologists and other professionals can use this quick and reliable measure when screening for intellectual disabilities or intellectual giftedness, or for other purposes:

• Screen to determine if in-depth intellectual assessment is needed
• Reassess after a comprehensive evaluation
• Estimate Full Scale IQ (FSIQ) scores in busy practice settings
• Assess cognitive functioning of individuals referred for psychiatric evaluations
• Provide FSIQ scores for vocational, rehabilitation, or research purposes
