Supporting Your Child as a Dual Language Learner: A Guide for Families of Young Children is a new resource from Californians Together designed to help families navigate their child’s multilingual journey from the early years through K–12 education. The guide helps families understand common language-related terms, how schools and early learning programs support multilingual children, and why home language development is critical to academic success, identity, and belonging. It also offers practical guidance for choosing early learning programs, understanding elementary school language program options, and advocating for bilingual education opportunities. Grounded in research and written with families in mind, this resource affirms that multilingualism is an asset and highlights how early language development can lead to long-term opportunities, including the State Seal of Biliteracy.
