English as a Second Language (ESL) can be seen as a branch of the broader tree of language education, which encompasses various programs designed to support language acquisition. These programs, including dual language programs, immersion programs, transitional bilingual programs, and sheltered instruction, each serve different purposes and approaches to language learning. While ESL focuses specifically on teaching English to non-native speakers, the other programs may incorporate multiple languages and cultural contexts. Thus, ESL is part of a larger framework aimed at enhancing language skills among diverse learners.
