Superintendent's Message

Superintendent Mat Holton
Dear Chaffey District Students, Parents, and Guardians,
It has been an exciting 1st semester, with students excelling in academics, music, drama, and athletics. I am so proud of the way students and staff are continually demonstrating new and innovative ways to overcome the obstacles presented by the COVID-19 pandemic during the past two and a half years. Teachers, counselors, and administrators at each school site are continuing to provide remediation opportunities for anyone who may still be struggling. They want every student to succeed, and they are available to help in any way that they can. Please call or email your teacher or school administrator if you need any assistance.
Students in the Chaffey District are completing their 1st semester of the 2022-2023 school year and preparing to take finals on Tuesday, Wednesday, and Thursday, December 20th – 22nd (these are minimum days). Please see your school’s webpage for further details. Friday, Dec. 23rd is a non-student day.
Students, I want to encourage you to finish 1st semester strong and then enjoy your much-deserved winter holiday break. Remember, if you need any help as you prepare for finals, it will be important for you to take advantage of interventions such as tutoring and individualized help during class time or teachers’ office hours.
Parents, please make sure that your student is using our 24-hour tutoring resource, Paper, if they need any help. If they encounter any difficulties along the way, please feel free to call your school or the District office (909-988-8511 ext. 2501) with any questions or concerns; we are happy to assist you. You may also check the “Resources” tab on our website for information about technology support, mental health services, and more. I want to thank you for the positive encouragement and support you have provided for your student and their teachers during 1st semester. The resilience and tenacity our students have demonstrated during the past few years provide me with confidence that we will overcome any new hurdles, develop new skills, and amaze ourselves as we expand our expertise in navigating this ever-changing world. Thank you for your dedication and your patience.
Again, I want to thank you for the support and encouragement you continue to show our staff. We recognize all that you have done, and will continue to do, to assure your student’s success this year. We sincerely thank you! We commit to do all we can to help every student reach their goals.
Please do not hesitate to reach out to teachers, counselors, administrators, or my office if you need any support.
Happy Holidays.
Mathew Holton, Ed.D.
All CJUHSD students will graduate ready for college and careers.
