Dear Chaffey District Parents and Families,
 
The 2025–2026 school year is off to a wonderful start! On Wednesday, August 6th, we were thrilled to welcome more than 25,000 students and staff back to our campuses, including the Class of 2029. From the excitement of meeting new friends to reconnecting with familiar faces, positive energy was felt in every classroom, hallway, and courtyard. We can’t wait to witness all the successes our students will achieve in the months ahead.
 
At the Chaffey District, our mission is to provide every student with the academic, social, and emotional tools they need to thrive both now and in the future. Students are encouraged to take advantage of the many opportunities available to enrich their learning experience. These include expanded academic programs, daily tutoring, wellness centers, health and counseling services, mentoring, and access to technology. Our team has worked hard to ensure that these supports meet the diverse needs of our students. If you would like more information about these resources, please connect with your school’s counselors or office staff.
 
We also understand that each student’s learning journey is unique. That’s why we offer a variety of alternative programs, including the Chaffey District Online High School and our Independent Study Program, to help students succeed in the learning environment that’s right for them. If you’d like to explore these options, your school’s counselor or administrator can help you get started.
 
I look forward to working together with families this year to make sure students are actively engaged in their learning and have ample opportunities to explore their passions – whether through academics, clubs, athletics, or other activities. Our shared goal is to prepare them with the knowledge, skills, and confidence they need to excel in college, career, and life.
 
Thank you for the partnership, encouragement, and trust you show our staff each day. Parents, your support plays a vital role in your student’s success, and we truly value all you do.
 
Mathew Holton, Ed.D.
Superintendent
Chaffey Joint Union High School District
