Ontario Jaguars, Parents, and Community Members,

The 2026–2027 school year is off to a great start, and I am incredibly proud of the energy, enthusiasm, and Jaguar pride our students and staff have brought to campus. It has been exciting to see our classrooms filled with learning, our students reconnecting with friends and teachers, and our school community coming together once again. Thank you to our parents and families for your continued partnership and support as we begin another successful year at Ontario High School.

Jaguars, I want to challenge each of you to make this year your best year yet. Attend school every day, arrive to class on time, complete your assignments, ask questions, and give your best effort in every class. Success does not happen by accident, it comes from consistent effort, perseverance, and a willingness to accept challenges. Whether your goal is college, a career, military service, or another path after high school, the work you do today is preparing you for your future.

Students and families should also know that you are never alone on this journey. Our teachers, counselors, administrators, support staff, and entire Jaguar family are here to help. Students are encouraged to build relationships with their teachers, take advantage of tutoring and extended learning opportunities, participate in clubs, athletics, and activities, and ask for assistance whenever it is needed. Parents and guardians can support this work by regularly monitoring attendance, grades, and academic progress through Aeries, Canvas, and ParentSquare and by maintaining open communication with our staff.

As we continue our pursuit of excellence, the California School Dashboard remains an important tool for understanding our progress. The Dashboard provides information about school performance in areas such as academic achievement, graduation rates, college and career readiness, attendance, and school climate. We will use this information not simply as a measure of where we are, but as a guide for where we need to go. I encourage our families and community members to visit the California School Dashboard to learn more about Ontario High School’s performance and progress.

Our goals this year are clear: increase student achievement, improve attendance, strengthen college and career readiness, maintain a safe and welcoming campus, and ensure that every student feels connected, supported, and prepared for life after graduation. Reaching these goals will require all of us students, staff, parents, and community partners working together with a shared commitment to excellence.

There is something special about being an Ontario Jaguar. Our students are fortunate to attend a school that offers caring and dedicated educators, rigorous academic programs, career pathways, athletics, clubs, activities, extended learning opportunities, and a community committed to helping them succeed. I challenge every student to take advantage of these opportunities. Get involved, discover your strengths, build lasting relationships, and make your time at Ontario High School count.

Parents and community members, thank you for trusting us with the education and development of our students. Your partnership is essential to everything we accomplish. Together, we will continue on the “Path of the Jaguar” and ensure that every student has the opportunity to achieve their goals in high school and beyond.

It’s a great year to be a Jaguar!

Sincerely,
Larry Rook
Principal, Ontario High School
