Summary

Rios Elementary is a K–5 school in El Cajon’s Cajon Valley Union district, serving 255 students; it is the third-smallest of 10 nearby schools. The most important academic finding is a sharp contrast between fourth- and fifth-grade math: in 2025–2026, 56% of fourth graders were proficient, compared with 20% of fifth graders, a 36-point gap.

Overall, the school’s strongest comparison is in math: its 40% proficiency was 1 point above the state and well above the district, while its ELA result of 43% was 7 points below the state and science at 33% was 3 points below. Rios exceeded district rates in all three subjects—by 12 points in ELA, 17 in math and 10 in science. Among nearby schools reporting all-grade scores, Rios was about even with the average in math, but 3 points below in ELA and 4 points below in science. Fourth-grade math stands out positively, while fifth-grade math is below the state rate by 17 points; fifth-grade ELA was also 9 points below the state.

Results have improved since 2022–2023: ELA proficiency rose by 20 points, math by 19 and science by 9. Math moved from 14 points below the state to 1 point above, though ELA and science remain below it. SchoolDigger ranked Rios at the 52nd statewide percentile (3 stars) in 2025–2026, up from the 17th percentile in 2023–2024. Context for families: the 2024–2025 student–teacher ratio was 21.2, the second-lowest among nearby schools with reported figures, while 76% of students were reported as free/reduced lunch eligible—the highest nearby share with the same measure and year. SchoolDigger’s group rankings indicate notably different relative results: Rios ranked at the 77th percentile for Hispanic students, versus 52 overall, and at the 9th percentile for White students. These are rankings of how well the school serves each group, not judgments about students.
