Summary:

Rio Elementary serves 5,250 students across nine schools—seven elementary and two middle schools covering grades K–8—with enrollment averaging 583 per school. In 2025–2026, the schools’ average proficiency was 32% in ELA, 24% in math and 22% in science, compared with California’s 49%, 38% and 36%. The group averages trailed the state by 17 points in ELA, 14 in math and 14 in science. The clearest overall finding is that Rio del Sol was the only school above the state result in all three subjects.

Rio del Sol stands well ahead of the other schools: its proficiency was 58% in ELA, 46% in math and 39% in science, leading the other eight schools’ averages by 29, 24 and 20 points, respectively. SchoolDigger ranks it at the 68th percentile and gives it 3 stars. Rio Del Mar is a strong second-tier option, ranking second in math (33%) and science (31%); its ELA result was 35%. At the lower end, Rio Plaza Elementary had the group’s lowest ELA (19%) and science (7%) results, and SchoolDigger places it at the 5th percentile with 0 stars. Rio Rosales had the lowest math result among K–5 schools (17%) and the second-lowest ELA result (23%); its SchoolDigger ranking was at the 11th percentile.

Recent progress is uneven: from 2024–2025 to 2025–2026, the average was essentially unchanged in ELA and math and rose 3 points in science, while California’s results rose about 0, 1 and 3 points, respectively. Rio Del Mar gained 9 points in science, while Rio Rosales fell 9 points in ELA and 8 in math. Similar enrollment and reported free/reduced lunch eligible measures in 2024–2025 do not mean similar results: Rio Del Mar had 499 students and 76% eligible, compared with 557 students and 77% at Rio Rosales, yet led by 13 points in ELA, 16 in math and 10 in science. These all-grades comparisons combine different school grade spans, so families may also want to consider grade-specific results.
