School Overview

River Islands High is a charter high school serving the River Islands master-planned community in Lathrop, a fast-growing city on the edge of the San Joaquin Valley where newer suburban neighborhoods sit alongside waterways and open space. The school skews stronger in math than in English or science, making it a decent fit for families who prioritize quantitative skills, though it's still finding its footing academically as the surrounding community continues to develop. Families drawn to the River Islands development — with its planned feel, newer housing, and proximity to both Stockton and the Bay Area via Highway 5 — will find this school very much a product of that same build-it-as-you-go energy.
