Summary:
Schools in ZIP code 93036 include 11 schools serving 9,855 students, from elementary through high school, plus one alternative school; most are in the Rio Elementary district, while the high schools are in Oxnard Union High. Results vary substantially among nearby schools, even within the same district. The clearest takeaway is that the elementary schools have a wide grade-5 performance spread, and the group average is below the state in ELA, math, and science.
Rio del Sol is the standout elementary school: its grade-5 results are 57% in ELA, 35% in math, and 44% in science, leading local elementary schools in all three subjects and beating the state in ELA and science. At the other end, Rio Plaza Elementary posts 21%, 7%, and 7%, respectively—28, 30, and 28 percentage points below state results. The gap between those schools is 36 points in ELA, 28 in math, and 37 in science. Among middle schools, Rio del Valle Middle leads Rio Vista Middle in all three grade-8 subjects, though both are below state results. At high school, Oxnard High leads Pacifica High in grade-11 ELA, math, and science; its math advantage is 11 points.
Across the 10 non-alternative schools, average all-grade results rose from 2024–25 to 2025–26 by about 2 points in ELA, 2 in math, and 4 in science, but several schools had declines in at least one subject. SchoolDigger’s statewide ranking places Rio del Sol at the 68th percentile and Rio Plaza at the 5th; over three years, Rio del Sol moved up from the 64th percentile, while Rio Plaza fell from the 11th. Context may help families compare schools, but does not explain results: in 2024–25, free/reduced lunch eligible shares were 55% at Rio del Sol and 83% at Rio Real Elementary, whose grade-5 results were notably lower. Providence, the small alternative school, reports low chronic absenteeism alongside a lower graduation rate and higher dropout rate; its ELA and science results are suppressed.
