Summary
Rio Vista Elementary serves 486 students in grades K–6 in Canyon Country, in the Saugus Union district. In 2025–26, its all-grade proficiency rates were above California’s in ELA, math and science, though below its district’s in all three. The most important concern is the uneven performance by grade: third-grade ELA proficiency was 33% and third-grade math was 37%, while fifth-grade ELA was much stronger at 69%.
Science is the school’s clearest strength compared with nearby schools, the district and the state. In 2025–26, 57% of students were proficient in science—21 percentage points above the state, 14 points above the nearby-school average and just 1 point below the district; Rio Vista ranked fourth among the ten nearby schools. ELA and math show a tougher local picture: ELA proficiency was 51%, above the state by 2 points but below the district by 16 and nearby average by 7. Math was 44%, above the state by 5 points but below the district by 20 and nearby average by 9. Rio Vista ranked seventh of ten nearby schools in both ELA and math.
Results have shifted in different directions over time: from 2022–23 to 2025–26, ELA fell from 56% to 51%, math was essentially flat at 44%, and science rose from 44% to 57%. SchoolDigger gives Rio Vista a 66th-percentile statewide standing, a rank of 1,995 out of 5,804 and three stars; it ranks sixth among the ten nearby schools. The 2024–25 student–teacher ratio was 27, the second-highest among those schools. Also in 2024–25, 77% of students were free/reduced lunch eligible, the third-highest nearby rate; California provides free meals to all students, and this is a separately reported eligibility measure. SchoolDigger’s student-group rankings flag a sharp change for English Language Learner Students: the school was at the 13th percentile in 2023–24, down from the 83rd percentile in 2022–23, compared with its overall 68th-percentile standing in 2023–24. For Special Education Students, its ranking fell from the 87th percentile in 2023–24 to the 59th in 2025–26, while its overall standing that year was the 66th percentile.
