Short Description of Instrument

The WASI is a quick, reliable measure of intelligence for use in clinical, educational, and research settings. The WASI is nationally standardized, yields the three traditional Verbal, Performance, Full Scale IQ scores, and is linked to the Wechsler Intelligence Scale for Children®—Fourth Edition (WISC–IV®), and the Wechsler Adult Intelligence Scale®—Third Edition (WAIS®–III). The WASI provides you with more information than you can typically receive from other brief intelligence tests.
The WASI consists of four subtests; two verbal (Vocabulary and Similarities) and two nonverbal (Block Design and Matrix Reasoning).
Administration: Paper-and-pencil, individual, face-to-face, requires examiner training.
Completion Time: Four-subtest form, 30 minutes; two-subtest form, 15 minutes.
Publication Date: 1999.
Ages / Grades: Individuals 6:0–89:11.
Norms: Standardization data were collected from a large nationally repre- sentative sample of children and adults from 6 to 89 years. Research data link the WASI with WISC–IV and WAIS–III in order to increase its clinical utility.
Advantages: Provides a quick but reliable and valid estimate of IQ when administration of a full battery is not feasible or necessary; particularly useful for research applications; easy to learn and administer

Scoring

Scores: VIQ, PIQ, and FSIQ scores.
Scoring Options: Hand scoring.
