Adolescent English language learners present particular challenges for schools. The population of adolescent ELLs is diverse, and their educational needs are affected by differences in immigration status, quality of educational background, native language, cultural distance from U.S. culture, future plans, and economic status. The article offers five practices that can help schools improve educational achievement for these students: acceptance of shared responsibility by school staff; a dual curriculum that promotes language development as well as academic needs; careful consideration of how to integrate immigrants with the general school population; extended learning time; and individual progress records.
