Summary

Ruth O. Harris Middle serves grades 7–8 and enrolls 562 students in Bloomington, California; it is the smallest school in a comparison group of 11 nearby middle schools. The most important concern is that its 2025–2026 proficiency rates were below the state, Colton Joint Unified, and the nearby-school average in all three tested subjects, with the greatest shortfall in science.

ELA is Harris’s strongest result relative to its comparisons, while science is its weakest. ELA proficiency was 29%, compared with 49% statewide and 34% districtwide; it was 6 points below the nearby-school average, and Harris ranked fifth-lowest among the 11 schools. Math was 15%, below the state’s 38%, the district’s 20%, and the nearby average by 5 points; Harris ranked second-lowest nearby. Science was 11%, compared with 36% statewide and 20% districtwide, and 10 points below the nearby average. Harris had the lowest science result in the nearby group.

ELA and math have improved over four reported years: from 2022–2023 to 2025–2026, ELA rose 12 points and math rose 8, while the state gains were 3 and 4 points, respectively. Science rose 4 points over that period but fell from 12% in 2024–2025 to 11% in 2025–2026, while the state result continued to rise. SchoolDigger ranked Harris at the 13th percentile statewide in 2025–2026, with 1 star; its percentile has recovered from 5 in 2022–2023, but remains second-lowest among nearby schools. Its 2024–2025 student-teacher ratio was 19.7, the group’s second-lowest, and 86% of students were free/reduced lunch eligible that year. SchoolDigger’s subgroup rankings show a notably stronger relative standing for African American Students: the school ranked at the 56th percentile in 2025–2026, versus the 13th overall. Its Homeless Students ranking fell from the 66th percentile in 2023–2024 to the 22nd in 2025–2026, a 44-point drop.
