Comprehensive Assessment of Spoken Language

Elizabeth Carrow-Woolfolk, Ph.D.


The CASL assessment is an ideal measurement of delayed language, spoken language disorders, dyslexia, and aphasia. It is an individually administered, research-based oral language assessment battery. The CASL is appropriate for those ages 3 through 21.

The CASL provides a precise picture of language processing skills and structural knowledge, allowing you to document development from preschool through the post secondary years. Because the CASL provides age-based norms, it satisfies Individuals with Disabilities Education Improvement Act (IDEA) requirements for identifying language impairment.

This test battery consists of 15 tests that measure language processing skills—comprehension, expression, and retrieval—in four language structure categories: Lexical/Semantic, Syntactic, Supralinguistic, and Pragmatic.

This flexible and easy to administer instrument can be completed in just 30 to 45 minutes. You have the option of giving only the tests you need for a given child. The CASL requires no reading or writing—children can respond to items by speaking, pointing, or marking their response choices with an X. Back to the top How to Use the Assessment
The CASL can be administered individually or as a group. Using information found in the manual you can draw clinical conclusions from the results of each one. All CASL tests are classified as either core or supplementary, depending on the age of the child assessed. Core tests measure the most representative aspects of each language category, while supplementary tests provide additional diagnostic information for use in quantitative and qualitative analyses. For several CASL tests, Descriptive Analysis Worksheets are available, allowing you to target specific skill areas for intervention.

Test Books are self-standing and tabbed for quick, easy reference. Administration guidelines are printed on the first few pages of each book. Convenient Record Forms, one for ages 3 through 6 and another for ages 7 through 21, provide space for profile analysis, item responses, scores, and behavioral observations.
