I'm new in this high school, I'm a student who's in ELD and still learning English, and also I play a sport, mt. Diablo is giving me the opportunity to play a sport and also being involved in learn English while I play. The teachers are good, and all of them are confident of what are they teaching also they are very patient. The food that is provided is good enough, but could be better for some students who doesn't have the opportunity to bring lunch to the HS.

In my freshman year, there were a lot of school activities like rallies and spirit week that was well organized. There are a lot of resources available to get help. I am now in a college now program when I am enrolled in Diablo Valley College and Mount Diablo Highschool because I had a teacher that recommended the program to me. I like how involved teachers are with their students.

I liked the community, they were very welcoming. But the community is also the problem. Homophobics, racists, you name it. Things I would change is the food. Come on now why is the food worse than elementary?

This school has potential and could be better than what it is. The school is in Concord but serves the kids of Bay Point which is a far more ethnically diverse area than Concord. As a result of “white flight” , nearly 80% of the students who reside in concord and are supposed to feed into Mt. Diablo...

This school is horrible. I would not recommend sending your child here. There are gangs, drug problems, and other things that are just horrible. The school is so easy, and has no challenge at all. I doubt any colleges would want you if you have a diploma from here.
