The National Center on Cultural and Linguistic Responsiveness provides the Head Start community with research-based information, practices, and strategies to ensure optimal academic and social progress for linguistically and culturally diverse children and their families. Young children who are dual language learners (DLL) are the largest growing segment of the U.S. population; therefore, the National Center on Cultural and Linguistic Responsiveness provides culturally responsive, user-friendly materials and training for staff and families to use to promote strong language and literacy skills in children’s home language and in English. On NCCLR’s Web site you will find “Ready for Success: Supporting Dual Language Learners in Head Start and Early Head Start”
