WASI-II Subtests
The WASI-II comprises four distinct subtests, each targeting specific cognitive abilities. These subtests are carefully designed to provide a comprehensive assessment of cognitive functioning, enabling clinicians, educators, and researchers to gain valuable insights into an individual’s strengths and weaknesses. The four subtests are⁚
- Vocabulary⁚ This subtest measures verbal comprehension and knowledge of word meanings. It involves presenting the examinee with a series of words and asking them to define or provide synonyms for those words. This subtest assesses an individual’s verbal fluency, vocabulary richness, and ability to understand and express complex ideas.
- Similarities⁚ This subtest assesses abstract reasoning and the ability to identify commonalities between concepts. The examinee is presented with pairs of words and asked to explain how they are similar. This subtest taps into an individual’s capacity for logical thinking, categorization, and conceptual understanding.
- Block Design⁚ This subtest evaluates nonverbal reasoning and spatial visualization skills. The examinee is presented with a set of colorful blocks and asked to arrange them to match a specific design presented in a stimulus book. This subtest requires visual-motor coordination, spatial reasoning, and the ability to mentally manipulate objects in three dimensions.
- Matrix Reasoning⁚ This subtest measures nonverbal reasoning and problem-solving abilities. The examinee is presented with a series of incomplete visual patterns and asked to identify the missing piece from a set of choices. This subtest assesses an individual’s ability to recognize patterns, analyze relationships, and make logical deductions.
Each of these subtests contributes to the overall assessment of cognitive ability, providing a comprehensive understanding of an individual’s strengths and weaknesses in different cognitive domains.
Administration and Scoring
The WASI-II administration and scoring process is designed to be efficient and straightforward, allowing for a quick and accurate assessment of cognitive abilities.

The examiner presents the stimuli, records the examinee’s responses, and scores each subtest according to specific guidelines.
The WASI-II offers flexibility in administration, with options for a four-subtest form, requiring approximately 30 minutes, or a two-subtest form, taking about 15 minutes. This flexibility allows for tailored assessments based on the specific needs of the individual and the goals of the evaluation.
The scoring process involves converting raw scores, representing the number of correct answers, into scaled scores and T scores. These standardized scores allow for comparisons across different age groups and facilitate the interpretation of results within a broader context. The WASI-II manual includes tables for converting raw scores to scaled scores and T scores, simplifying the scoring process.
The manual also provides guidance on interpreting the scores, highlighting the significance of each subtest score and their relationship to overall cognitive functioning. It emphasizes the importance of considering the examinee’s background, history, and other relevant factors when interpreting the results, ensuring a comprehensive and nuanced understanding of the individual’s cognitive abilities.
Interpreting WASI-II Scores
The WASI-II Scoring Manual provides comprehensive guidance on interpreting the scores obtained from the four subtests⁚ Vocabulary, Similarities, Block Design, and Matrix Reasoning. It emphasizes the importance of understanding the strengths and weaknesses of the examinee’s cognitive profile, considering both the individual subtest scores and their combined contribution to overall intellectual functioning.
The manual highlights the significance of each subtest in reflecting specific cognitive abilities. For instance, Vocabulary assesses verbal comprehension and knowledge, while Similarities evaluates abstract reasoning and verbal fluency.
