Best Public Schools in Oceanside, CA

Oceanside, California, has 38 schools: 22 elementary, six middle, six high and four alternative schools, serving students from elementary grades through high school and alternative programs. Results vary considerably among schools and subjects: middle-school averages were 36% in ELA, 25% in math and 24% in science, compared with state results of 49%, 38% and 36%. The clearest overall takeaway is that a citywide label would hide major differences—among K–5 schools, math scores ranged from 25% to 73%, a 47-point gap.

Mission Vista High led the conventional high schools in all three subjects, with 88% in ELA, 52% in math and 66% in science—about 39, 14 and 31 points above state results. Among K–5 schools, Empresa Elementary had the highest math score, 73%, while Ivey Ranch Elementary led in ELA at 66% and science at 51%. At the other end, Jefferson Middle had the lowest middle-school scores in all three subjects: 25% in ELA, 13% in math and 16% in science. Surfside High (Continuation) also stands out as a concern: chronic absenteeism was 94%, versus 18% statewide, and its graduation rate was 61%, versus 88% statewide. Mary Fay Pendleton Elementary is another bright spot, with a SchoolDigger ranking in the 92nd percentile and five stars.

Recent changes are mixed rather than uniform. Oceanside High improved from 2024–25 to 2025–26 by 8 points in ELA, 5 in math and 9 in science; its ELA result moved from below the state to above it, though math remained 13 points below. SchoolDigger’s three-year percentile ranking rose from the 37th to the 59th percentile at South Oceanside Elementary, while Martin Luther King Junior Middle fell from the 68th to the 53rd. The reported low-income measure is free/reduced lunch eligible (FRL), school year 2024–2025: 55% at Mary Fay Pendleton and 41% at Empresa, among schools with strong results; these figures are context, not an explanation of performance. Comparisons across schools have limits because grade spans and programs differ.
