Principal's Message

Azande Aikens
Dear Rancho Families,
As we approach the crucial testing period in the coming months, I want to emphasize the significance of our students' performance and the vital role Rancho Cucamonga High School plays in supporting their success.

In April, our juniors and seniors will be participating in the California Assessment of Student Performance and Progress (CAASPP), beginning on April 2nd. The CAASPP exam is an essential indicator reported on the California Dashboard, reflecting the academic progress and achievements of our students. This assessment provides valuable insights into our students' academic progress and helps us tailor our educational programs to meet their needs effectively.

To ensure a smooth testing process, our school will implement a block testing schedule from April 8th - April 11th. This schedule is designed to minimize disruptions to regular classes while allowing our students to focus on their assessments.

In May, we have the Advanced Placement (AP) exams, with the testing window spanning from May 6th - May 17th. These exams offer our students an opportunity to demonstrate their mastery of college-level material and potentially earn college credit, reflecting positively on their academic records.

I urge all parents/guardians and students to stay updated on important announcements and information regarding testing through Canvas and Parent Square. These platforms will provide detailed schedules, resources, and any additional support available to ensure our students feel prepared and confident during these critical assessment periods.

As a final reminder, please note that Spring Break will take place from March 25th - March 29th. I hope everyone enjoys a well-deserved break and returns refreshed and ready to tackle the challenges ahead.

Thank you for your cooperation and continued partnership.

Cougar Pride,
