Adult Education

Welcome to the office for Adult Basic Education (ABE), High School Equivalency (HSE) and English Language Acquisition (ELA). Our mission is to provide free, quality instructional programming and support services to help adults learn English and civics, improve reading, writing, math skills and prepare to pass high school equivalency exams.

Students who successfully complete our programs acquire the skills necessary to improve employment opportunities, advance to further education or training and are more involved in their communities.

Classes are offered in more than 25 locations throughout our district. Chances are we are in your neighborhood – let us help you take that next step. Contact us at (630) 942-3697 or email
