About Us

The Chaffey Joint Union High School District serves the communities of Ontario, Montclair, Rancho Cucamonga, and portions of Fontana, Upland, Chino, and Mount Baldy. With over 25,000 students, the District is the fourth largest high school district in California. 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.
 
The Chaffey Joint Union High School District Board of Trustees are steadfast in the belief that "Nothing is more important than student learning and their achievement."
 
Our daily purpose encompasses our commitment:
"To provide student learning, and ultimately their achievement, of the prescribed curriculum that takes place in the classroom under the direction of the teacher." The Chaffey District supports this daily act. We realize that our efforts uniquely influence the future of our community and of this nation, and we are passionate about doing whatever it takes to prepare students to be successful and contributing citizens of the 21st century.
 
The Chaffey District has provided a quality education for high school students in the area since 1911. As the District continues to grow and progress, we are poised to meet the challenge of providing the finest quality education possible for every student. 
All CJUHSD students will graduate ready for college and careers.

Principal's Message

Portrait of Principal Jerome Rucker
Hello Lions,
 
We are almost at the end of 1st semester; it is important that students continue to finish strong academically. Progress grade reports have been mailed home, and it is imperative that all students and parents use that information to monitor progress in each class.  Please continue to monitor Canvas and communicate with teachers and counselors if you have any concerns.
 
I encourage students to take advantage of our tutoring center, open Monday – Thursday, after school until 4:30 PM in the library, along with the many tutoring opportunities our teachers provide. Parents, please continue to help students by reviewing their progress each day and by ensuring their homework is complete.  
 
Finals will be held Wednesday, Thursday, and Friday, December 17th-19th (these are minimum days).  All students should begin preparing for finals each night by reviewing the content they have learned.

To the Alta Loma Community, have a great holiday season!  Please enjoy the winter break, and we look forward to seeing students return on Monday, January 5, 2026.
 
Run Towards the Roar,
