Our Purpose

Sierra High School is celebrating 29 years of educational excellence this 2012-2013 school year. Located on the east side of the Harrison Community, Sierra High School has an excellent academic program and continues to maintain its reputation for academic and athletic success. The students and staff are high achievers who embrace the support of the school's community in a team effort to prepare tomorrow's leaders for success.

The school offers many educational opportunities for students to expand their knowledge and talents. In addition to classes in core curriculum areas, students may choose to participate in advanced placement classes, honors classes, junior/senior job fairs and a wide variety of elective courses and extracurricular activities. 

Throughout the school year, Sierra utilizes the school action plan as a means to focus efforts toward improving student achievement.  While there is still work to be done on raising student achievement, Sierra students have made great gains in academic growth according to the Longitudinal Student Growth Model measurement used by the Colorado Department of Education.

Our Educators

The primary goal of the Sierra staff is to foster a learning environment where a positive attitude toward school and learning is prevalent. The Sierra staff is a committed team of educators who continually study the best instructional practices and go above and beyond to meet students' needs. Classroom teachers and administrators meet on a monthly basis to align curriculum, review student achievement data, make improvements and give feedback on the progress of various educational programs. Sierra values high quality teachers and offers many opportunities for professional development to all staff members.

Dedicated staff members sponsor many clubs and programs that provide opportunities for students to expand their growth and interests.

Our Students

Our students are proud to be Sierra Stallions! Sierra recognizes the importance of creating lasting relationships with students, families and the community. The school has a long tradition of establishing community partnerships that are instrumental in providing educational and social opportunities for students, families and staff. Sierra believes it takes a community to ensure academic success for all students. Teachers, parents, students and administration must work together as one, with an open mind committed to communicating the needs of the student.
