Ventris Learning, in collaboration with university faculty, linguists, and practicing speech-language pathologists, is engaged in a multi-year project to update the Diagnostic Evaluation of Language Variation (DELV), a standardized and linguistically unbiased measure of language ability. The revised DELV is scheduled to be released in early 2028. Updates will include:
The resulting next generation DELV tests will be even more useful to SLPs in accurately identifying language disorders/delays in children ages 4.0-9.11.
