Great teachers for English beginners and applicants for new jobs and immigration. Students with different English level could learn a lot via the ESL classes and also meet new friends during the courses. Enough covered parking spaces for students who drive to the classes. The classes rooms and campus are both very clean.

This is a belated thank-you note. I’ve been studying at Chino Valley Adult School since Level 3. Before I entered, I couldn’t even make a full sentence. But now I can talk freely about daily life. Thank you to Chino Valley Adult School for empowering my English skills, and thank you to my teacher Peggy — she is one of the best teachers there. She has many years of professional English teaching experience. She always takes care of each student’s feelings and often shares local culture and social customs, which makes it easier for students to understand and use English in different contexts. I’m truly grateful to America, CVAS, and my teacher Peggy. Thank you.

Peggy Thompson, my Level 3 teacher, is truly an amazing teacher. Her classes are always fun and engaging, and I can honestly say she is the best English teacher I’ve ever had. She explains the lessons using simple words and even body language, which makes it much easier for me to understand the material. She has such a deep knowledge of English, and I’m so impressed that she remembers the names of all 40+ students in our class, including new students who just arrived. I feel very lucky to be in her class, and I’m confident that with her guidance I will continue to improve my English.
