Bilingual education programs improve students' academic outcomes compared with English-only instruction.

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

Partly. Evidence is mixed and mostly partial: one Ethiopian comparative study and a California advocacy report support bilingual education's potential to improve outcomes, while a Chinese university study found no significant difference and a Texas district study cites research that English-only instruction reduces academic success. No item provides a general, definitive comparison across populations.
