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.

Superintendent's Message

Mat Holton, Superintendnet
Dear Chaffey District Parents and Guardians,
The Chaffey District has completed the first week of the 2020-2021 school year in historic fashion. Students were excited to connect with their teachers and peers as they began instruction through Canvas, the District’s new learning management system. We are so thankful for the patience, grace, and understanding shown by students, parents, and staff members as we all adjusted to the new learning model. Although we will continue to meet virtually for the unforeseen future, we look forward to the day when we will gather in-person once we are able to physically return!
The week of August 10th will begin our first full week of instruction. On Monday mornings, students should log in to Canvas and check each of their classes for information and updates from their teachers. Teachers will have posted their assignments and work for the week so students will know what to expect. Teachers will clearly indicate all assignments the students should complete. Students will begin working in Canvas on Monday morning as if they were on their normal bell schedule and continue independently working on assignments until 12:15 p.m. when they log in and attend their 2nd period class. This 20-minute class session is required, and teachers will take attendance. Monday afternoons are set aside for students to get academic support or complete academic work independently. Teachers will have office hours, small group collaboration opportunities, and will be available for students who need assistance. 
Tuesdays – Fridays the students will follow their normal block schedule for Distance Learning (available on each school site’s webpage).
Although the start of this school year was far different than any traditional first day of school in the history of this District, our staff was excited to welcome each student back and provide them with the academic and emotional support they will need to succeed. I look forward to partnering with all of you to make sure that students are engaging in their schooling in healthy and constructive ways, and I look forward to working with your student! We are doing everything we can to make sure students are safe and get to learn in healthy and supportive environments, and we will keep everyone informed as schedules and local and State directives shift.
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 contribute to do, to assure your student’s success this year, and we sincerely thank you!
Stay safe!
Mathew Holton, Ed.D.
