CLAS is an archived site, as funding has ended. While the information shared is relevant and useful it is not being updated. The CLAS Institute identified, collected, reviewed, cataloged, and described materials and practices developed for children and families from culturally and linguistically diverse backgrounds, and professionals who work with them. CLAS created a resource bank and catalog of validated, culturally and linguistically appropriate materials, and of documented effective strategies, for early intervention and preschool services. Information in several languages.
