Principal's Message

Portrait of Principal Jerome Rucker
Dear Students and Parents/Guardians,

Welcome to the 2025-2026 school year! As we embark on this new journey together as Lions, I challenge each student to show up everyday and approach their learning as scholars. With students back on campus, we are committed to taking every precaution to maintain a safe and healthy environment for both students and staff.

Our mission at ALHS is to prepare every student for success in college and careers. We empower our students with a foundation of essential skills, including Technology, Career Exploration, Employability, Learning, and Life Skills. Our dedicated faculty is here to support your growth, ensuring you can confidently communicate the skills you develop throughout your four years at ALHS.

Our goals for this school year are to be student focused, data driven, and human centered. I encourage all students to take full advantage of the numerous resources and tutoring opportunities we offer. The library is open daily, both before and after school along with tutoring. For more details on these services, please visit our website.

Lions, remember that consistent attendance is key to your success. Ensure you are following the bell schedule, arriving to class on time, actively participating in discussions, and submitting your assignments promptly. Families, we kindly ask that off-campus appointments be scheduled outside of school hours to maximize class attendance.

Parents and guardians, our combined role in your student’s success is crucial. Your involvement helps foster a strong partnership between home and school. For parents who are interested in becoming more engaged, we have our PTSA that will meet on campus on August 25th at 5 pm. We also offer Coffee with the Principal, Popcorn with the Principal, AAPAC, ELAC, and LCAP opportunities for parents to get involved. Please reach out to Dr. Adam Stites, AP of Achievement, who coordinates parent engagement opportunities throughout the year. Dr. Stites also sends out a weekly newsletter filled with opportunities for parents to get involved in the ALHS community. As a reminder, all parents/guardians and campus visitors must present state identification when visiting the campus during school hours.

This is a special time at Alta Loma High School, which is the perfect time for your students to attend our school. From our amazing student leadership programs, VAPA, ASL program, to our robust AP course offerings Alta Loma High School is the premiere place for your student to attend. Our Club Rush is scheduled for September 10th and many of our sports teams will soon be hosting tryouts.

If you have any questions or need assistance, please contact our office staff. We are here to support you and look forward to a fantastic year ahead.

Run Towards The Roar,
Principal Rucker
