Home language support is the foundation for developing English language skills. Today’s early childhood staff must be prepared to enhance experiences for a growing number of young children who are learning their home languages and English. We can promote positive experiences for these children by holding high expectations and emphasizing their strengths, including cultural and linguistic strengths. We also provide children and their families with the individualized learning supports necessary to succeed in school. All early childhood program staff want to understand what young dual language learners (DLLs) need in order to thrive in Head Start and beyond. These DLL Toolkit resources give teachers, caregivers, and family services staff support to foster the learning and development of young children.
