GreatSchools Rating
The GreatSchools Rating helps parents compare schools within a state based on a variety of school quality indicators and provides a helpful picture of how effectively each school serves all of its students.

We also advise parents to visit schools, consider other information on school performance and programs, and consider family needs as part of the school selection process.

I attended Chaffey for all 4 years and was heavily involved in the arts and honors programs. I felt that I was very prepared and had all the resources and i needed from my teachers.

Chaffey is a school full of many opportunities be it for a hobby or workforce. The ability to both be involved with the school, academics, and theatre allows for such creativity and interest. Personally, students tend to fight more now than when I first started as a student but that is more of a student issue rather than chaffey. Overall the experience is great

My experience at Chaffey High School has been absolutely great. This school has granted me many opportunities to get involved and make friends. They have various programs that help bring students together. I have been in a leadership program for two years here at Chaffey and it has been the best. It has helped me gain so much confidence throughout my high school years. I have been able to build bonds with not only students but teachers as well. I am also part of the ETS program offered in the Chaffey District. This program has helped me a lot with my journey into college. My advisors have provided me with support. This school has many resources to offer. The worst parts of this school are the disobedient students that cause trouble. I would like to see more helpful and productive ways to help bad behavior.

Chaffey High School is an outstanding school, and in my opinion, one of the best high schools in the area. The school leadership, under Mrs. Martinez, is outstanding with administrators who truly care about the safety of students and preparing them for college and careers. The Saturday School progra...
