Summary
Del Rio Elementary is a K–5 school in Oceanside, California, serving 353 students in Oceanside Unified. Its latest results put it just above California’s state averages in English language arts (ELA), math, and science, though performance differs considerably by grade. The most important takeaway is that these near-state results mark a substantial improvement from several years ago, not a record of consistently strong results.
ELA is Del Rio’s strongest overall comparison with nearby schools: its 51% result is close to the nearby average of 51%, and it outscored 4 of 9 schools. Math and science are weaker relative to neighbors: Del Rio’s 39% in math was 8 percentage points below the nearby average of 47%, while its 36% in science was 5 points below the nearby average of 41%; it outscored 3 of 9 schools in each subject. All three results were just above the state averages, and above the district averages by 6 points in ELA, 5 in math, and 4 in science. Fourth grade stands out, with ELA at 62% and math at 54%; third-grade math is a concern at 32%, 15 points below the state.
Results have risen since 2022–2023: ELA increased 21 percentage points to 51%, math rose 16 points to 39%, and science climbed 14 points to 36%. SchoolDigger’s overall ranking improved from the 26th percentile and 1 star to the 58th percentile and 3 stars in 2025–2026, placing Del Rio around the middle of nearby schools; it ties Mission Meadows Elementary and is below some local schools. SchoolDigger’s statewide measure for Low Socio Economic Status Students reached the 69th percentile in 2025–2026, compared with the school’s overall 58th percentile, indicating stronger results in serving that group. The English Language Learner Students measure was at the 64th percentile in 2021–2022, compared with 32nd overall that year. In 2024–2025, 82% of students were free/reduced lunch eligible, the second-highest share among nearby schools with that measure; California also provides free meals to all students statewide, so these are separate facts. Del Rio’s 23.5 student-teacher ratio was virtually identical to the nearby average.
