What school district is Diamond Ranch High School part of?

I currently attend this school. It has a strong set of teachers in the Spanish and English departments. As for the rest of the subjects, I feel as though it comes down to the student''s motivation to want to learn. Even in my current Honors class, there are people that just seem to have no motivation to even attempt their work. It all comes down to this one saying, You can lead a horse to water but, you can''t make it drink. I have an older sibling who attended Garey High School and managed to get into one of the top UCs out there. If you want to learn it comes down to your own willingness to learn. As long as you have the motivation and help from teachers and/ or tutors you should be fine. :) We are currently in the middle of a pandemic but I feel as though this school year hasn''t been the worst. Hopefully, I can enjoy senior year in person and be able to give this school a higher rating. I have one last comment: DO TUTORING IF YOU NEED THE HELP OR ASK YOUR TEACHER TO HELP EXPLAIN IT!!!!!!!!!!!!!!!!!!!!! Don''t be afraid to ask for help. :D (I am also in the VAPA program through art at the moment and it''s been good so far. Sometimes Mr. Crockett gets a little off-topic though lol. )
One of the best high schools in the Pomona Unified District. A very high, rigorous, and challenging academics and athletic programs. Their is a strong Music Department and a variety of after-school programs and clubs. Their is tutoring all the time with the teachers and clubs that offer tutoring.
As a former teacher of Diamond Ranch High School, I must say that unless your child attends the honor and/or AP classes offered at this school, he or she will get very little out of this school due to mismanagement by the administration and the misappropriation of funding.
