 Foreign-language education programs can provide native speakers of English with exposure to a second language, but TWI has the potential to help students achieve near fluency in a second language.That suggests that such programs are not solely to ELLs to acquire English, but they aim to develop second language proficiency for native speakers of English.In fact, because two-way immersion requires almost an equal amount of native English-speakers and native Spanish-speakers, a lack of native English-speakers makes it unlikely that such programs will not be implemented.
