The Foundation for Child Development has issued a new policy brief summarizing research on the best way to serve preschoolers who are not native English speakers. In some states, more than 50% of preschool age children fit this description. The brief challenges a number of myths and offers some research-based guidelines for policy makers. The brief also says that effective approaches must be used from pre-K to third grade if they are to work. This is a quote that caught my attention:

Systematic, deliberate exposure to English during early childhood combined with ongoing opportunities to learn important concepts in the home language results in the highest achievement in both the home langauge and English by the end of Third Grade and beyond.

Seems like all kids could benefit from a "deliberate" program that helps them become linguistically fluent and learn important concepts.
