As we embark upon the fourth and final quarter of the school year, I am delighted to witness the unwavering dedication our students continue to display in their pursuit of learning. It is inspiring to see excellence not only in academics but also in athletics and the arts. I am thrilled to share some remarkable achievements: six of our schools secured positions in the top ten in the annual Academic Decathlon competition, several athletic teams have been victorious in CIF and State championships, two schools were recognized as Distinguished Schools by the California Department of Education, and our drama, dance, choir, and band programs are flourishing. My sincere appreciation goes out to our exceptionally talented students and staff for their outstanding contributions!
 
The progress we have achieved thus far fills me with pride, and I eagerly anticipate the promising developments that the remainder of the school year holds.
 
Our dedicated teachers have been working diligently to prepare students for the upcoming California Assessment of Student Performance and Progress (CAASPP)/California Science Test (CAST), as well as the Advanced Placement (AP) exams. The CAASPP is a pivotal assessment for all juniors, evaluating proficiency in Math and English, while the CAST is designed for all seniors, measuring their success in science. Both tests play a crucial role in gauging the overall success of our schools. I strongly encourage our juniors and seniors to attend each testing day, giving their best effort to display their college readiness. The CAASPP/CAST and AP testing schedules are posted on each school’s website.
 
To our students, I urge you to remain steadfast in your studies and strive for your personal best as you conclude this academic school year. Parents and guardians, please continue to monitor your student’s progress through Canvas, and feel free to reach out to teachers, counselors, administrators, or my office if you require any support. We are committed to doing everything possible to assist students in achieving their goals.
 
Lastly, please note that there will be no school in session during the week of March 25-29. I hope everyone enjoys a safe and rejuvenating spring break.
 
Thank you for your ongoing dedication and support.
 
Sincerely,
 
 
Mathew Holton, Ed.D.
Superintendent
