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.

Principal's Message

Christina Martinez
Dear Students, Parents, and Guardians, 
 
Welcome to the 2021-2022 school year! We look forward to welcoming our incoming 9th graders, the Class of 2025, and all our students to in-person instruction this fall! We know that we have many students who will be coming to campus for the first time and we can’t wait for them to enjoy our beautiful facilities. Expect to see staff and a student leaders from band, ASB, Cheer, Link Crew, and more out in front of the school as we kick off the school year and welcome our Tigers to Chaffey High.
 
Please look for your summer mailer through the US postal service to arrive no later than July 16.  Please read all the documents enclosed, and make sure that all the forms in the registration packet are completed and bring them to turn in on registration/schedule pick-up day.  Students will begin to report the last week of July for Schedule pick up.  See the schedule below for exact  dates and times.  For parents/guardians of 9th and 10th graders, we invite you to attend our Tiger Parent Meeting.  This presentation will take place on the same day as your student’s schedule pick-up and focus on how to help your student become academically successful in high school and beyond.  
 
Parents and guardians, your role in your student’s development is a huge part of their success. Your involvement helps to build a healthy partnership with the school. If you would like to do even more, please reach out to Dr. Merianne Segovia, AP of Achievement, for parent engagement opportunities throughout the year.
 
Finally, beginning this school year, the hours for all schools in the Chaffey Joint Union High School District will shift to 8:30 a.m.-3:20 p.m. Friday hours will be from 9:30 a.m.-3:20 p.m. This shift to a later start time is to prepare for the legally mandated late start for California high schools in 2022. If your child will need transportation to arrive to and from school, please fill out the transportation application on our website.
 
As always, please feel free to contact me with any questions and enjoy the rest of your summer. 
 
Go Tigers!
