English as a Second Language
English as a Second Language
In ESL classes, students learn to understand, speak, read, and write in English for many reasons: to get a job, get a better job, go to school, become citizens, help their children in school, or live more successfully in the United States. Class lessons are based on students’ needs and interests. Classes are offered in person and through a remote, distance-learning option. Each level is one-year; students do not need to register again once they are enrolled in the class for the year.
After completing the online registration form, students are given an assessment to determine proper placement. Open enrollment is available on a "space available" basis.

MODES OF LEARNING
Chaffey Adult School ESL classes are conveniently located at two sites in the city of Ontario. ESL classes are available at no charge. We offer two modes of learning English.
Most students learn best when receiving direct instruction from a teacher in the classroom. Quality online and/or distance-learning options are accessible to students who prefer this way of learning or whose work, childcare needs, or other barriers exist to prevent in-person attendance.
