Instruction in Monroe 2-Orleans BOCES ENL program, formerly known as English as a Second Language (ESL), emphasizes English language acquisition. In our ENL program, language arts and content-area instruction are taught in English using specific ENL instructional strategies. Some content area classes are Integrated ENL classes. Students receive core content area and English language development instruction, including the use of the home/primary language as support and appropriate ELL instructional supports to enrich comprehension. In a stand-alone ENL class, students receive English language development instruction taught by a NYS-certified teacher of English to Speakers of Other Languages (ESOL) in order to acquire the English language needed for success in core content areas.
