Summary

Roberts Ferry Charter School Academy is a K–8 school serving 169 students in Waterford and the surrounding area. In 2025–26, its all-grade proficiency rates were above California’s in English language arts (ELA), math and science, with its largest state advantage in math. The most important caution is a pronounced sixth-grade dip: ELA proficiency was 31%, 17 points below the state, and math was 27%, 10 points below.

Overall, the school is stronger than the state in all three subjects: ELA proficiency was 57% versus 49% statewide, math was 53% versus 38%, and science was 44% versus 36%. Its scores exactly matched those reported for the Roberts Ferry Union Elementary district, so they show no school-level edge over the district. Among nearby K–8 schools with reported results, Roberts Ferry ranked third of six in ELA, fourth of six in math, and third of five in science. It scored above the nearby-school average in all three subjects, but its local standing was most modest in math.

Results have risen since 2022–23—by 6 points in ELA, 6 in math and 4 in science—but the path has not been steady: from 2024–25 to 2025–26, ELA fell 2 points and math 5, while science rose 7. SchoolDigger ranked the school 1,612th of 5,804 statewide, at the 72nd percentile with four stars; its percentile was down 8 points from the prior year. SchoolDigger’s subgroup rankings varied notably: White Students ranked at the 43rd percentile in 2025–26, 29 points below the school overall and down 29 points from the prior year; Low Socio Economic Status Students ranked at the 96th percentile in 2024–25, compared with the school’s overall 80th percentile that year. For context, the 2024–25 student-teacher ratio was 21.1, the second-highest among nearby K–8 peers with reported ratios, and 37% of students were eligible for free or reduced-price lunch.
