Product Details

Test items are designed to focus on the main area of interest (synonyms, antonyms, idioms, etc.) to reduce or eliminate the need for memory where possible.


  • Quickly isolate the specific skill, category, or processing ability to be assessed.
  • Leverage stable and reliable results over time and across raters, with strong internal consistency and test-retest and interrater reliability.
  • Evaluate response to intervention (RTI), using the CASL-2 to track improvement over time.
  • Answer a variety of referral questions including eligibility for speech services, placement in special education, determining if a language delay or disorder is present, or measuring language abilities in English language learners.


CASL-2 includes instructions, examples, pictures, items, prompts, sample correct and incorrect answers, and scoring criteria to streamline the administration process.

  • All new normative data and more extensive clinical groups so you can confidently use CASL-2 with a wide range of individuals.
  • 14 individual tests that cover the ages between 3 and 21 (the Paragraph Comprehension test has been removed).
  • 10 tests to be used with children between 3 and 6.
  • Alternative scoring guidelines for African-American dialect.
  • Updated record form design that makes scoring easier and includes an Item Analysis Worksheet for each test, to help develop intervention plans and write IEP goals.
  • Easy-to-remember start and stop rules that are consistent across all tests.
