About Our School

Los Osos High School

The doors of Los Osos High School first opened to students in August of 2002, and since then, we have been on a mission to inspire and achieve excellence!  In what is now our tenth year, we have become solidly entrenched as one of the premier schools in the Inland Empire and our students have produced the highest Academic Performance Index (API) scores of any comprehensive high school in San Bernardino and Riverside Counties every year that we have been in existence--a testament to the passion for continual improvement in all endeavors that is embraced by our students, staff, and parents.    

Student learning is our top priority and not only do Los Osos students excel in the classroom, but Grizzlies have proven to be high performing in the arts and athletics; their outstanding achievements in these fields complement their academic studies and promote our students’ overall growth and development.  Our award winning visual and performing arts programs are second to none and our athletic programs are extremely competitive and already have claimed numerous Baseline League championships along with a few coveted CIF individual and team championships!  Most importantly, Los Osos students are expected to be role models and our school provides a bustling and extremely spirited student activities program that allows every student an opportunity to become involved in Grizzly life.  All of these activities allow students to find a connection at school, to contribute to our community, and to learn to lead by example and grow through hard work.  Los Osos High School is quickly closing in on a decade of excellence and the future looks even brighter!
