Summary:

ZIP code 92880 has three middle schools in Corona-Norco Unified, all serving grades 7–8. In 2025–2026, the schools’ average proficiency was above the state average in English language arts (ELA), math, and science, but the results differed sharply by school. The most important finding is that Dr. Augustine Ramirez Intermediate and River Heights Intermediate were above the state in all three subjects, while Auburndale Intermediate was below it in all three.

Ramirez led in ELA, at 69%, and science, at 55%; it was 20 percentage points above the state in ELA and 19 points above in science. River Heights narrowly led all-grade math: its 56.2% was 0.4 points above Ramirez’s 55.8%, and 18 points above the state. Auburndale scored 39% in ELA, 19% in math, and 18% in science—10, 19, and 18 points below the state, respectively. Its results were also 28 points below the other two schools’ average in ELA, 37 points in math, and 32 points in science.

Results improved overall from 2024–2025 to 2025–2026: the three-school average rose about 4 percentage points in each subject. All three schools improved in math and science; ELA rose at River Heights and Auburndale, while Ramirez declined by about 1 point. SchoolDigger rankings for 2025–2026 place Ramirez in the 84th percentile, River Heights in the 88th, and Auburndale in the 28th. Staffing ratios do not mirror the score pattern: in 2024–2025, Ramirez and River Heights each had a 26.6 student-teacher ratio, while Auburndale’s was 21.0. All three report free/reduced lunch eligible figures for 2024–2025: 59% at Ramirez, 69% at River Heights, and 89% at Auburndale; these are context, not an explanation for scores. In 2025–2026, chronic absenteeism was 8% at Ramirez, 10% at River Heights, and 22% at Auburndale, compared with 14% districtwide and 18% statewide.
