Principal's Message

Welcome to Chaffey Adult School! I’m thrilled and honored to serve as your new principal. Adult education holds a special place in my heart. My parents, Chilean immigrants, learned English and technical skills in adult schools much like CAS leading to increased financial stability and opportunities for our family as well as a lifetime of gratitude for the amazing adult school teachers, counselors, and staff.

Our theme for this year is We Are Here, and it’s my goal to continue to raise awareness of the fantastic programs available at your local adult school for free or for a very low cost. CAS is by far the best educational deal in town, and has been for over 57 years! Please consider partnering with us to make your educational hopes and aspirations a reality.

CAS offers programs in High School Equivalency (HSE/GED) test preparation, High School Diploma, English as a Second Language (ESL), Citizenship, Parent Education, Vocational and other non-credit classes. Chaffey Adult School is WASC Accredited and an authorized GED testing center. Classes are located at our main campus, 1802 E. 7th Street in Ontario, and at our satellite campus, 557 W. 5th Street in Ontario. Other classes are scheduled throughout the communities of Ontario, Montclair, and Rancho Cucamonga.

Please contact us if you have any questions, and know that we are here for you!
