Welcome to San Marcos High School!
As the flagship high school of the San Marcos Unified School District, SMHS proudly serves over 3,100 students from San Marcos and nearby communities. Nestled near Cal State San Marcos and Palomar College, we partner with these institutions to create a strong academic bridge between high school and higher education.

Our students thrive in a wide range of award-winning Career Technical Education (CTE) pathways and specialized programs, including Healthcare, Robotics, Engineering, TV News Production, Digital Video Production, Computer Science, and more. These hands-on experiences equip students with the skills they need for college and careers.

At SMHS, we believe every student can succeed. We offer robust academic support, including AVID and a full selection of Honors and Advanced Placement (AP) courses. Beyond the classroom, students are encouraged to get involved — with over 100 clubs, competitive athletic teams, and an award-winning performing arts program, there’s something for everyone.

Our dedicated teachers meet weekly to collaborate and strengthen instructional practices, always with the goal of increasing student achievement and supporting the whole child.

San Marcos High School is proud to serve its community and provide a comprehensive, well-rounded high school experience.
