About Us

Diamond Ranch High School is the home of the Panthers! A state-of-the-art high school in the hills where Diamond Bar and Pomona meet.

Our vision is "to prepare students to become first class citizens with a world class education!" Key components that enable us to stand out as one of the great high schools of our region include: academic prowess; numerous AP and Honors courses; Digital High School status; cutting-edge technology; athletic success; and powerful co-curricular programs. DRHS was honored by being named as one of the "great schools" in California for achieving significant growth on the Academic Performance Index. We were one of the top ten academic growth schools in the Inland Empire. We are proud to be a California Distinguished School. We recently received a six-year WASC accreditation term. Congratulations to our students, teachers, parents and community.
