Welcome to Horizon High School

Generic HOH Front V2

Horizon High School is committed to excellence on all fronts — academic achievement, arts, athletics and co-curricular activities. Horizon balances a holistic liberal arts education with rigorous content-specific curriculum to equip students for success beyond graduation.

Teachers and staff get to know students as individuals, guiding them through the wide variety of academic experiences at Horizon. Academically, students are challenged to think critically and problem solve. During their high school years, Horizon students develop a strong work ethic that empowers them to take responsibility for their choices, decisions and future.

In a safe, caring community, Horizon fosters global thinking and transformative experiences that shape students for success in the 21st-century world.

The Five Star Education Foundation works closely with the Adams 12 Five Star Schools by forging partnerships and raising money to invest in student success. In collaboration with the district and business community, we fund opportunities that inclusively prepare students for a variety of options after high school, ranging from learning-readiness, to post-secondary education, to students directly entering the workforce. We have halted all overhead fundraising to address the immediate needs of our students and our community as we face COVID-19 together.​
