The CASL-2 measures oral language processing skills of comprehension and expression across four categories: lexical/symantic, syntactic, supralinguistic, and pragmatic. It preserves the strengths of the original and highly regarded CASL, yet offers the most up-to-date measure of oral language skills available. Use the CASL-2 to evaluate response to intervention or track improvement over time.
