Superintendent's Message

Mat Holton
Dear Chaffey District Parents and Families,

The Chaffey District began the 2023-2024 school year on Wednesday, August 9th. Over 25,000 students and staff members (including the incoming freshman class of 2027) arrived on campus to joyfully reconnect with their peers after summer break – the positive energy and anticipation of what the new school year will bring was evident in the faces of everyone on campus. We are excited to see the incredible things our students will achieve this year.

The District is committed to providing students with the academic, social, and emotional support they will need to succeed both throughout their time in our schools and in their lives after. We offer extensive supports to students and encourage them to take advantage of the District’s many programs designed to enhance their educational experience. As students in our District, they have access to expanded learning opportunities, daily tutoring, physical and mental health provisions, wellness centers, mentors, and technology devices and support. We pride ourselves on the robust systems we have put in place to address students’ complex needs; information regarding these  services and supports can be provided through school site office staff and counselors.

Additionally, we offer alternative academic programs for students who would benefit from this type of instruction. If you would like information on our Chaffey District Online High School, Independent Study Program, or other  alternative educational options, please contact your school’s counselor or administrator.

I look forward to partnering with you to make sure that students are engaged in school and are provided ample opportunities to pursue their interests through instructional classes, clubs, and extra-curricular activities offered at their school site. Our goal is to equip them with the skills necessary to reach their full potential as they pursue their college and/or career goals. 

Again, I want to personally thank you for the support and encouragement you continue to show our staff. Parents, we recognize all that you have done, and will continue to do, to assure your student’s success this year, and we sincerely thank you!
Mathew Holton, Ed.D.
Chaffey Joint Union High School District
All CJUHSD students will graduate ready for college and careers.
