Summary
Rio San Gabriel Elementary is a 747-student K–5 school in Downey, California, in the Downey Unified area. Its clearest strength is third grade: among 11 nearby schools, Rio led in ELA at 67%, ahead of Cresson Elementary at 63%, and ranked second in math at 70%, behind Cresson at 75%. Results look very different by fifth grade: Rio’s math proficiency was 32%, below the state’s 37% and district’s 43%; only Gauldin (A.L.) Elementary scored lower nearby. The most important takeaway is that strong third-grade results do not carry through consistently to fifth grade, especially in math.
Across all grades, math is Rio’s strongest subject relative to the state and district, while science is its weakest against nearby schools. Rio’s math proficiency was 49%, compared with 38% statewide and 44% in the district; its 49% ELA result beat the state’s 49% by about 7 points, but was about 1 point below the district. In science, Rio was at 37%, about 1 point above the state and nearly level with the district, but 4 points below the nearby-school average of 41%; it ranked ninth of 11 schools. Rio’s ELA and math results were above the nearby averages of 53% and 47%, respectively.
Proficiency has risen over the longer term: from 2022–2023 to 2025–2026, ELA increased by 5 points, math by 3, and science by 8. Chronic absenteeism also fell sharply, from 41% in 2021–2022 to 15% in 2025–2026, below both the state (18%) and district (20%). SchoolDigger ranks Rio 1,862 of 5,804 California schools (68th percentile, 3 stars); its student-teacher ratio is 25.7, the highest among nearby schools. In 2024–2025, 73% of students were free/reduced lunch eligible, compared with a nearby-school average of 78%. SchoolDigger’s statewide measure places Rio at the 87th percentile for how well it serves Hispanic students, compared with the school’s 68th-percentile overall standing; its 41st-percentile standing for how well it serves students in special education is notably lower.
