Chaffey High School was exactly what we wanted for our children. They all played sports and we wanted them to be able to play any sport they wanted all throughout high school. Chaffey sports programs allowed for that to happen. they did not have them specialize in one sport, all of our children were able to play as many sports as they wanted, sometimes 5 or 6 in one year.

My experience in chaffey high school is a really cool story for me especially that I have so many experiences and events that I have done or have. Many things about this school is that there are so many different cultures in our school that are involved in different clubs and our campus is so diverse and densely populated with many students. I really enjoyed my experience in chaffey and with my new found confidence to go to college and know what I'm going to do with my career and life.
