It has eight comprehensive high schools, a continuation high school, an online high school, a community day school, an adult school, and alternative programs. The District offers a wide variety of instructional options that provide a quality education for each student, every day. The District's well-prepared, dedicated, and highly qualified teachers and support personnel are second to none.

Montclair High School is one of eight comprehensive high schools in the Chaffey Joint Union High School District and is located in the incorporated community of Montclair, approximately 45 miles east of Los Angeles in San Bernardino County.

Montclair High School offers a comprehensive curriculum with elective offerings in Business, World Language, Fine Arts, Home Economics and Industrial Technology. Additionally, we also offer courses in the Junior Reserve Officer Training Corps (JROTC) program, Academic Decathlon, Virtual Enterprise, and Advancement Via Individual Determination (AVID). MHS is an AVID National Demonstration School; 536 students are enrolled in the program. In April, Montclair High School was honored in receiving the Gold Ribbon Award and the Title 1 Academic Achieving Award for helping our students achieve their potential.  In November, we were awarded the Golden Bell Award given by the California School Board's Association for our AVID Program for its school-wide implementation to support all targeted groups. Comprehensive after-school activity and athletic programs provide students with an opportunity to participate in academic, social and athletic events throughout the year. Montclair also offers a comprehensive counseling program that guides students in the development of academic, career and personal/social needs to maximize their individual potential. The guidance team has been recognized by the state for establishing a superior program.  Accredited by the Western Association of Schools and Colleges (WASC) in 2013, MHS received a 6-year accreditation with a one-day mid-term review.
