Three Rivers Union Elementary

Three Rivers Union Elementary has one school, Three Rivers Elementary, serving kindergarten through grade 8 in an area with 93 students enrolled at the school. With no other schools in the district list, there is no local school-to-school comparison. The clearest finding is that in 2025–2026, the school’s all-grade results were above California’s in ELA, math, and science.

Three Rivers Elementary is the only school, so it is not meaningfully the area’s top or bottom performer compared with local peers. Against the state, however, its 2025–2026 results were strong in all three subjects: 63% in ELA versus 49% statewide, a 14-point lead; 48% in math versus 38%, a 10-point lead; and 50% in science versus 36%, a 14-point lead. Science had the widest advantage, just ahead of ELA. In the reported grade-level comparisons, the school also exceeded same-grade state results: its advantage ranged from 8 points in seventh-grade ELA to 23 points in third-grade ELA, and from 4 points in seventh-grade math to 13 points in third-grade math.

Math shows the biggest improvement over time: the school moved from 8 points below the state in 2024–2025 to 10 points above it in 2025–2026, as its result rose from 29% to 48%. ELA rose from 60% to 63%, while science increased from 44% to 50%; both were above the state in both years. SchoolDigger ranks the school 1,071st of 5,804 statewide, in the 82nd percentile with four stars; its percentile ranking went from 78th in 2023–2024 to 58th in 2024–2025 and then 82nd. Other context: the school’s 2024–2025 student–teacher ratio was 15.5, and 37% of students were free/reduced lunch eligible in 2024–2025. Reported chronic absenteeism in 2025–2026 was 11%, compared with 18% statewide.
