Summary:
This analysis examines four high schools within the Colton Joint Unified School District, serving grades 9-12 in a high-need area where most students qualify for free or reduced-price lunch.
Among the comprehensive high schools, Grand Terrace High School at the Ray Abril Junior Edal Complex stands out with the highest graduation rate, best English scores, and lowest chronic absenteeism. Colton High has shown notable improvement in its statewide ranking, while Bloomington High faces greater challenges in English proficiency. All three of these schools graduate students at rates well above the state average, indicating strong support systems, but they share a significant district-wide struggle with math proficiency, where scores are roughly half the state average.
Slover Mountain High (Continuation) serves a distinct at-risk population and operates with very different metrics, including much higher per-student funding and a lower student-teacher ratio to address its students' needs. For parents, the data suggests that while the district's high schools effectively support students toward graduation, academic achievement, particularly in mathematics and for Spanish-speaking learners, remains an area for focused improvement across the community.
