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.

Superintendent's Message

Mat Holton, Superintendnet
Dear Chaffey District Parents and Guardians,
 
The Chaffey District has begun the 2020-2021 school year in historic fashion – virtually! We are almost half-way through the first quarter, and I want to thank you for the positive encouragement and support you have provided for your student and their teachers. Together, staff and students have learned to navigate Canvas, our new learning management system, and meet each day on Zoom for instruction. I am proud of our students and staff members for creating new and innovative ways to learn and grow together. During this season of distance learning, and even when we transition to a hybrid model, we will continue to encounter new challenges, develop new skills, and amaze ourselves as we expand our expertise in navigating this digital world we find ourselves in. Thank you for your persistence and your patience.
 
A major key to success is communication and daily engagement. Especially while we are in a distance learning format, it is easy to lose touch and fall behind. I want to assure you that our staff is here to help your student stay connected and provide them with the resources they need to be successful. Please make sure that your student is using our three primary technology platforms: Outlook, Canvas, and Zoom. If they encounter any difficulties along the way, please feel free to call your school or the District office (909-988-8511 ext. 2501) with any questions or concerns; we are here to assist you. You may also check the “Resources” tab on our website for information about technology support, mental health services, and more.
 
Attendance is critical to your student’s success, whether we are meeting virtually or in person. Make sure that they are following the bell schedule, attending all Zoom meetings on their designated days, participating in class discussions, and turning in assignments on time.
 
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! I look forward to partnering with you to make this our best year ever!
 
Stay safe!
 
Mathew Holton, Ed.D.
