Superintendent's Message

Mat Holton
Dear CJUHSD Parents and Guardians,
As the 2023-2024 school year draws to a close, we find ourselves reflecting on the incredible journey we've had together. This academic year has been filled with challenges, triumphs, and countless moments of growth. As our students prepare for state testing, AP exams, and finals, we are continually impressed by their perseverance and dedication. The resilience they have shown over the past several years is truly remarkable, and we are proud of their commitment to success.
With Graduation just around the corner, we eagerly anticipate celebrating the accomplishments of the Class of 2024. (A personalized letter to the Class of 2024 will be posted on the website prior to graduation). Graduation dates and times for each school site can be found on our website under the Resources tab. To the seniors, you are the leaders of tomorrow, and we have never been more confident that our future is in excellent hands. We applaud you, Class of 2024, and we cannot wait to see the positive impact you will make on our world!
Once again, the Chaffey District will be offering summer school to provide students the opportunity to recover lost learning opportunities, remediate credits, and improve grades. Summer school will run from June 3rd to July 2nd, and students may contact their counselor to register.
As we turn our focus to the upcoming 2024-2025 school year, we are filled with excitement and optimism. With your continued support, we are confident that our students will thrive and excel in the year ahead.
Wishing you all a restful and enjoyable summer break.
Mathew Holton, Ed.D.
All CJUHSD students will graduate ready for college and careers.
