What Is the WASI-II and Its Purpose?
The WASI-II is a brief, reliable measure of intelligence designed to provide an estimate of an individual's cognitive functioning. It is commonly used in clinical, educational, and research settings for:
- Quick screening of intellectual abilities
- Preliminary assessment before more comprehensive testing
- Identifying cognitive strengths and weaknesses
- Supporting diagnostic decisions
The assessment comprises four core subtests, which collectively generate an overall Full Scale IQ score, as well as separate Verbal and Performance IQ scores. The manual accompanying the WASI-II is crucial for ensuring standardized administration and scoring.
