Principal's Message

Dear Cougar Families,
 
Welcome back to another incredible school year at Rancho Cucamonga High School! The school year is off to a great start, and we are thrilled to embark on a new journey of learning, growth, and achievement together. I would like to take this opportunity to share exciting news and important insights about our vision for the 2025–26 school year.
 
At Rancho, our vision is clear: All students will graduate college and career ready. This year, we are challenging our students to strive for excellence in all aspects of their high school experience. Whether it’s academics, extracurriculars, or personal development, we want our Cougars to aim high, work hard, and take ownership of their future.
 
To support this vision, we are focused on increasing the number of students meeting A-G requirements and reducing the number of freshman course failures. We have implemented a comprehensive system of support that prioritizes individualized academic assistance, social-emotional development, and a strong network of communication between school and home. We are committed to offering resources for both students and parents to ensure everyone has what they need to succeed.
 
One of the key tools in our shared journey is the California School Dashboard, which provides a detailed view of our performance across various areas, including academic progress, graduation rates, student engagement, and school climate. This information helps us celebrate our successes and identify areas for continued growth. We encourage you to explore the Dashboard to better understand how Rancho is performing and where we are focusing our improvement efforts.
 
The partnership between students, families, and staff is essential to achieving success. I encourage you to reinforce the importance of daily attendance, staying on top of assignments via Canvas, and maintaining open lines of communication with teachers. If you have not already, please make sure you have created a Parent Square account and installed the app to receive real-time updates and school-wide announcements.
 
We are proud of the strong academic programs, dedicated educators, and inclusive school culture that make Rancho Cucamonga High School such a special place. Our students are fortunate to be part of a community that genuinely cares for their success and prepares them for the opportunities ahead. Whether their next step is college, career, or both, we are preparing them to thrive in an ever-changing world.
 
Thank you for your continued trust, support, and partnership. Let’s work together to make this year one of the best yet for our students.
 
Cougar Pride,

Azande Aikens
