Summary

Rio Plaza Elementary is a K–5 school in Oxnard, California, serving 455 students in the Rio Elementary district. Its 2025–26 proficiency results were below the district and state in English language arts (ELA), math and science. Most importantly, it scored below every comparable nearby K–5 school in all three subjects.

Math is the school’s strongest subject relative to nearby averages, the district and the state, while science is weakest relative to nearby schools. Rio Plaza’s 2025–26 proficiency was 19% in ELA, compared with 36% at nearby K–5 schools on average, 35% in the district and 49% statewide. In math, it was 15%, versus 30% nearby, 26% in the district and 38% statewide. In science, it was 7%, versus 26% nearby, 23% in the district and 36% statewide. Grade-level results also point to particular challenges in fourth-grade ELA and fifth-grade math: Rio Plaza scored 9% and 7%, respectively, below all seven comparable nearby schools in those grades.

Results have declined overall since 2022–23: ELA proficiency fell 6 points to 19%, math fell 3 points to 15%, and science fell 2 points to 7%. The gaps with the state widened over that period, though ELA and math each narrowed their gap somewhat in the latest year. SchoolDigger ranks Rio Plaza in the 5th percentile statewide (rank 5,533 of 5,804) and gives it 0 stars; its percentile rose 1 point from the prior year but is down 9 points from 2022–23. Context includes a student-teacher ratio of 26.7 in 2024–25, higher than every nearby school reporting a ratio, and 88% free/reduced lunch eligible in 2024–25. One notable contrast in SchoolDigger’s group rankings: English Language Learner Students ranked at the 46th percentile in 2023–24, compared with the school’s overall 11th percentile, indicating a stronger relative showing for that group.
