Language support for students not fluent in English

The ESL (English as Second Language) program is designed to increase fluency in students with limited English ability. A student’s score on the admission English language assessment test, together with classroom observation, determines initial placement in the ESL program. Students are kept in ESL until ESL support services are no longer required. To be exited from ESL, the student needs to demonstrate the language and skills necessary to work independently in the mainstream classroom. All ESL students are required to attend summer school. An exit exam is offered near the end of Summer School in order to determine placement for the following year.
