Best High Schools in Zip Code 93030

Three high schools in ZIP code 93030—Rio Mesa High, Del Sol High, and Condor High—serve grades 9–12 in the Oxnard Union High School District. Across the schools, average proficiency in 2025–2026 was 39% in English language arts (ELA), 22% in math, and 26% in science—11, 16, and 10 percentage points below California, respectively. The clearest urgent concern is attendance at Condor: chronic absenteeism was 52%, versus 23% districtwide and 18% statewide.

The schools have different academic strengths: Rio Mesa leads in ELA at 46%, 17 points above Del Sol at 29%; Condor leads in math at 37%, 29 points above Del Sol at 8%, and in science at 29%, compared with Del Sol’s 22%. Del Sol has the lowest proficiency in all three subjects. Graduation results also favor Rio Mesa: its 94% rate is above Condor’s 89% and California’s 88%; no Del Sol rate is supplied.

Condor made the largest recent gains, rising 13 points in ELA, 34 in math, and 18 in science from 2024–2025 to 2025–2026, even as its attendance remains a concern. SchoolDigger’s rankings show a similar split: Condor rose 34 percentile points to 54, while Rio Mesa fell 7 points to 45; Del Sol is at 25. In 2024–2025, student–teacher ratios were 23 at Rio Mesa, 19.6 at Del Sol, and 19.1 at Condor. The schools’ free/reduced lunch eligible rates that year were 73%, 87%, and 76%, respectively; these figures provide context, not an explanation for results. Del Sol has no prior-year test results supplied, so the reported improvement trend does not cover all three schools.
