Comprehensive Assessment of Spoken Language
Age Range: 3 through 21
Completion Time: 30 to 45 minutes for the core battery
Scores/Interpretation: Age-based and grade-based standard scores (M = 100, SD = 15), grade and test-age equivalents, percentiles, normal curve equivalents (NCEs), and stanines.
Measure language skills thoroughly
Comprehensive Assessment of Spoken Language (CASL) is an individually and orally administered, research-based, theory-driven oral language assessment battery for ages 3 through 21.
Fifteen tests measure language processing skills—comprehension, expression, and retrieval—in four language structure categories: Lexical/Semantic, Syntactic, Supralinguistic, and Pragmatic.
- In-depth assessment capabilities provide a precise picture of problems with language processing skills and structural knowledge.
- Use CASL to record growth from preschool through the postsecondary years.
- Age-based norms identify language disorders and impairment as outlined by IDEA.
- Tests, composites, and indexes have high internal consistency and test-retest reliabilities.
No reading or writing required
Only a verbal or nonverbal (pointing) response is required. Reading or writing ability is not needed to respond to test items.
The CASL battery is ideal for measuring delayed language, oral language disorders, dyslexia, and aphasia.
CASL is flexible. Administer only the tests you need for a single subject. For example, an average five-year-old might be given four core tests, plus one or two supplementary tests, if warranted.
Core tests measure the most representative aspects of each language category for each of the six age bands.
Supplementary tests provide additional diagnostic information to yield assessment data for quantitative (profile) and qualitative (clinical) analyses.
Assess comprehension, expression, and retrieval in four oral language categories
Lexical/ Semantic Tests: Lexical/Semantic—knowledge and use of words and word combinations. Tests include: Basic Concepts, Antonyms, Synonyms, Sentence Completion, and Idiomatic Language
Syntactic Tests: knowledge and use of grammar (morphology and syntax). Tests include: Syntax Construction, Paragraph Comprehension, Grammatical Morphemes, Sentence Comprehension, and Grammaticality Judgement
Supralinguistic Tests: Supralinguistic—comprehension of complex language whose meaning is not directly available from lexical or grammatical information. Tests include: Nonliteral Language, Meaning from Context, Inference, and Ambiguous Sentences
Pragmatic Test: awareness of appropriate language in a situational context and the ability to modify this language as necessary
CASL Core and Supplementary Tests by Age Band
Fifteen tests let you measure specific aspects of oral language ability. You can administer Core tests (C) to derive a global language composite. Supplementary tests (S) provide you with additional diagnostic information and Index Scores.
|Comprehension of Basic Concepts||C||S|
|Paragraph Comprehension of Syntax||S||C||C||S|
|Sentence Comprehension of Syntax||C||S||S|
|Meaning from Context||S||C||C|
Descriptive Analysis Worksheets
Descriptive Analysis Worksheets are available for several CASL tests, enabling you to target specific skill areas within these categories for intervention.
These worksheets include a descriptive item analysis for the specified CASL tests, enabling clinicians to target more specifically the skill areas that may be problematic for an examinee. Information from the worksheets could be helpful in writing reports and IEPs. (Of course, other samples of language would be needed to confirm hypotheses concerning an examinee's strengths and weaknesses.) On each worksheet a recording system is suggested. Users should feel free to devise their own.

Test administration and scoring
Test Books: Three self-standing Test Books are tabbed for quick administration and easy reference. Key test administration principles are printed on the first few pages of each.
Two Record Forms: One for ages 3 through 6, the other for ages 7 through 21. Both forms provide space for a profile analysis, item responses, scores, and behavioral observations.
Manual: Complete details about CASL in this comprehensive volume.
Norms Book: Contains tables for converting raw scores to age-based standard scores, percentiles, stanines, NCEs, and test-age equivalents for CASL’s tests, indexes, and composites.
Testing Time: This varies with age band and the number of recommended core tests. Generally, the core battery takes about 30 minutes for children ages 3 through 5, and about 45 minutes for older individuals.
