Overview

The Comprehensive Assessment of Spoken Language, Second Edition is the most up-to-date measure of oral language skills available. It offers the flexibility of 14 stand-alone tests in one comprehensive yet specific battery. Preserving the strengths of the original and highly regarded test, the second edition introduces new and enhanced features to increase validity, functionality, and ease of use.

The CASL-2 shares the same underlying theory as the new Oral Passage Understanding Scale (OPUS) and the popular Oral and Written Language Scales, Second Edition (OWLS-II). Since all three tests are based on the author’s Integrative Language Theory, they provide a cohesive evaluation across a broad range of areas. While the OWLS-II provides an evaluation of oral and written language, the CASL-2 offers a more in-depth picture of 14 spoken language skills. The new OPUS measures listening comprehension and how well a person can apply these skills.

Applications and Uses

The CASL-2 can be used by speech-language pathologists and other professionals in settings such as schools, clinics, hospitals, private practices, and intervention programs. When you need to evaluate response to intervention (RTI), you can use the CASL-2 to track improvement over time. It can help answer a variety of referral questions, including eligibility for speech services, placement in special education, determining the presence of a language delay or disorder, or the measurement of language abilities in English learners. The CASL-2 provides important information for everyone involved in the treatment of children and young adults to reach their potential at school, at home, at work, and in the community.

What It Measures

For children and young adults ages 3 to 21, the CASL-2 measures spoken language across four structural categories:

• Lexical/Semantic: Knowledge and use of words and word combinations
• Syntactic: Knowledge and use of grammar
• Supralinguistic: Knowledge and use of language in which meaning is not directly available from the surface lexical and syntactic information
• Pragmatic Language: Knowledge of language that is appropriate across different situational contexts and ability to modify language according to the social situation

Within these categories, 14 stand-alone tests give you flexibility in measuring the specific areas of interest. Each test can be interpreted separately and/or test scores can be combined to get an overall picture of oral language skills. The CASL-2 tests feature extended age ranges to start assessment and intervention earlier, as well as track progress in a child over time. Besides the inclusion of younger ages, all tests now extend to the age of 21.

Test items are designed to focus on areas of interest (for example, synonyms, antonyms, idioms, and so on) to reduce or eliminate the need for memory where possible. This is achieved by using pictures and repeating words at the beginning and end of each item. Please see the table on 6 for a description of each test. The CASL-2 Pragmatic Language Test is particularly useful for measuring social communication skills in people with an autism spectrum disorder or social (pragmatic) communication disorder, it measures the ability to understand and apply societal rules and expectations. It is the only performance test that measures pragmatic language abilities in children under age 6.

Standard scores are available for the following:

• Each of the 14 tests (specific skill scores)
• Lexical/Semantic Index, Syntactic Index, Supralinguistic Index (categorical index scores)
• Receptive Language Index and Expressive Language Index (language processing index scores)
• General Language Ability Index (GLAI) (overall skill index score)

You can quickly isolate the specific skill, category, or processing ability that you want to assess. If a single score is needed for a student’s eligibility for speech services or placement in special education, the GLAI can be determined by administering just 4 to 5 tests. The back of each record form has a chart that shows required tests to obtain index scores based on the examinee’s age. Specific skill scores are available, such as descriptive ranges, confidence intervals, percentile ranks, test-age equivalents, and grade equivalents, to enhance detail and functionality. Index scores are also available as descriptive ranges, confidence intervals, and percentile ranks. Alternative scoring guidelines offer criteria for scoring results with individuals who speak with different dialects for accurate measuring.

How It Works

Using one of three self-standing test easels, read items aloud as the examinee responds by speaking or pointing. All easels feature full-color illustrations for more engaging administration, especially for young children, and use updated items to address current technology. The easels also include instructions, examples, pictures, items, prompts, samples of correct and incorrect answers, scoring criteria to streamline the administration process, and tabs to easily flip to needed tests.

There are two CASL-2 record forms, the Comprehensive Form and the Preschool Form, both described in the table (below). Using the appropriate form, record the examinee’s responses by hand. Across the 14 tests, suggested Start Items allow you to skip nonapplicable items dependent on the individual’s age. Consistent basal and ceiling rules (four correct items in a row and four incorrect items in a row, respectively) save time by making it easy to remember when to stop an administration.

Both CASL-2 record forms now include a fold-out panel to easily transfer raw scores to the Score Summary page for standard scoring conversion. Additionally, both forms include an Item Analysis Worksheet per test, providing qualitative information to help write IEP goals and intervention plans. It highlights the examinee’s strengths and areas of improvement, giving a level of detail that extends beyond a standard score.

FREE Online Scoring and Reporting

Upon purchase of a CASL-2 Kit or Form, you gain access to digital scoring and reporting through the WPS Online Evaluation System—at no additional charge! This gives you the option to score online and automatically generate useful reports, including a Score Report with Item Analysis, Progress Report, and Profile Summary Report. Time-saving and HIPAA compliant, WPS’s online testing platform lets you securely and conveniently keep a record of your administrations and share helpful information with parents, teachers, and others involved in treatment.

A recent study compared performance on the CASL-2 using remote administration vs. in-person, and the findings support the validity of remote administration, suggesting that both methods of administration should yield similar results.

Technical Information

Standardization for the CASL-2 is based on a sample of 2,394 individuals ages 3 to 21 years old. The sample is stratified to match recent U.S. Census data for gender, ethnicity, region, and parent education level, to confidently use the CASL-2 with a wide range of individuals. The CASL-2 and OPUS are co-normed, supporting the validity of both tests and making them wonderful companion tests. A clinical validation sample of 271 individuals demonstrates that the CASL-2 can differentiate between typically developing individuals and those with the following diagnoses:

• Expressive and/or receptive language disorder
• Hearing impairment
• Autism spectrum disorder
• Social (pragmatic) communication disorder
• Intellectual disability
• Learning disability
• Developmental delay

The CASL-2 has strong internal consistency and test-retest and interrater reliability, demonstrating the stability and reliability of results over time and across raters. Comparative studies with the CASL, OPUS, OWLS-II, and CELF-5 show that correlations are strong but differentiate enough to support that the CASL-2 measures unique aspects of spoken language.
