Bilingual education programs improve academic outcomes for English learners compared with English-only instruction.

Is it true that bilingual education programs improve academic outcomes for English learners compared with English-only instruction?

Partly. Evidence is mixed and only partial: a small bilingual-program study and a medical-vocabulary trial favor bilingual instruction, while a randomized trial found no significant English reading difference and a reference work reports transitional bilingual education is no better than other programs. None of the placed items directly compares bilingual versus English-only instruction on broad academic outcomes for English learners.
