25 Parent Reviews for Mount Diablo High School

Oh, it's not that bad! And this is coming from an antisocial nerd like myself. There's the right and wrong people to hang out with, and the wrong people don't want you to hang out with them if you don't want to. The academic programs are great, and a lot of the teachers do care. We have a leadership ...  Read more

Not the school to go to if your child is fluent in English but needs special education instruction. As with a lot of schools in California, they are overrun by ESL students and it makes it impossible for the teachers to do their jobs and actually teach academics. Kids that go to this school are disrespectful, ...  Read more

Middle and high school students also took subject-specific CSTs in math and science, depending on the course in which they were enrolled.
