Dear Chaffey District Students, Parents, and Guardians,
 
I hope you and your families enjoyed a refreshing winter break. As we welcome students back to campus, I am excited to mark the beginning of the second semester and to see the positive energy that comes with a fresh start to the new year.
 
With the third quarter already in full swing, this is an important time for students to remain focused and engaged. The months ahead provide valuable opportunities to build momentum, strengthen skills, and finish the school year strong. I am incredibly proud of the dedication our students continue to show in prioritizing their education, and I commend their perseverance and commitment to learning.
 
To our students: your hard work matters, and everyday counts. Please remember to take advantage of the many academic supports available to you, including your teachers, counselors, and tutoring resources, as you work toward your goals this semester.
 
To our parents and guardians: thank you for your continued partnership and encouragement. Your support plays a critical role in student success. Additional resources, including technology support and mental health services, are also available on the “Resources” tab of our website.
 
As always, I am grateful for the resilience of our students and the unwavering support of our families. Together, we remain committed to ensuring every student has the opportunity to thrive and achieve their fullest potential.
 
If you have questions or need assistance, please do not hesitate to contact teachers, counselors, or site administrators, at your school site. 
 
Wishing you a successful and rewarding second semester.
 
Sincerely,

Mathew Holton, Ed.D.
Superintendent
