• Welcome to Sierra High School, Home of the Timberwolves!

    Our student population of 1,600 reflects the diverse community of Manteca, located in the heart of the San Joaquin Valley.  Sierra High School is a dynamic and creative high school that constantly strives to prepare students for the world in which they will live and work. Our extra-curricular activities have been very popular with our students, as we offer a full complement of athletic, club, and co-curricular offerings.  One of our goals is to assist each student in getting connected with a program and mentor on campus to get them involved in the school community.

     Additionally, the Sierra High staff recognizes the need for ongoing professional development focusing on quality instruction to increase student achievement. Through the Professional Learning Community model, we will continue to explore avenues for our students to experience success and challenge them with rigorous and valid curriculum, which supports them in becoming college and career ready. Whether in the academic, extra-curricular, athletic, or visual and performing arts, we exist for our students. The Sierra High community is committed to working together to build upon our strengths, identify areas of need and put in the countless hours of dedication to make our school a better place for all students. Go T-Wolves!
