This interactive webinar introduces the Family Dual Language Learner (DLL) Support Guide, a user-friendly resource designed to help families and educators work together during the DLL identification process in the California State Preschool Program. Through real-world examples and discussion activities, participants learn how to use the guide to strengthen family–school connections, affirm children’s cultural and linguistic assets, and support biliteracy from the start. The recording also offers practical strategies for introducing and using the guide during family meetings and enrollment conversations.
