School Overview

Rio Mesa High sits in Oxnard, a working-class coastal city in Ventura County where the agricultural roots run deep and the Pacific is never far away. The school draws a predominantly Latino community and tends to shine brightest in science relative to its other subjects, which may appeal to families with students who lean toward hands-on or STEM-oriented learning. It's a solid neighborhood school for families planted in the Oxnard area who value a campus with strong community ties and a student body that reflects the city itself.
