Dear Chaffey District Parents and Families,

It has been an exciting beginning to the 2024-2025 school year. We welcomed over 25,000 students and staff back to campus on Wednesday, August 7th, including our new freshman class of 2028. The joy of reconnecting with friends and the excitement for the year ahead was evident in the faces of everyone on campus. We are eager to see the amazing accomplishments our students will achieve this year.

The Chaffey District is dedicated to providing our students with the academic, social, and emotional support they need to thrive both during their time in our schools and beyond. We encourage students to take full advantage of our wide range of programs designed to enhance their educational journey. This includes expanded learning opportunities, daily tutoring, mental and physical health resources, wellness centers, mentoring, and access to technology and support. Our District is proud of the comprehensive systems we have established to meet the diverse needs of our students. For more information about these services and supports, please contact your school's office staff or counselors.

We also provide alternative academic programs for students who may benefit from different types of instruction. If you are interested in learning more about our Chaffey District Online High School, Independent Study Program, or other alternative educational options, please reach out to your school’s counselor or administrator.

I am excited to partner with you to ensure that our students are fully engaged in their education and have numerous opportunities to explore their interests through classes, clubs, and extracurricular activities. Our aim is to equip them with the skills they need to achieve their full potential and successfully pursue their college and career aspirations.
 
Thank you for your continued support and encouragement for our staff. Parents, we truly appreciate all you do to ensure your student’s success in school!

Mathew Holton, Ed.D.
