School Overview

Aragon High sits in one of the more established, tree-lined pockets of San Mateo, drawing from neighborhoods where families tend to put down roots for the long haul — and the school reflects that stability. Academics are genuinely strong across the board, with science scores that rival some of the Bay Area's most competitive campuses, making it a natural fit for students with an eye toward STEM or rigorous college prep. San Mateo itself strikes a balance between Peninsula suburban comfort and easy access to both San Francisco and Silicon Valley, so families here get a grounded, community-feel school without feeling far from everything.
