Summary:
ZIP code 92058 has one listed middle school, Jefferson Middle, serving grades 6–8 and enrolling 441 students. Its 2025–2026 proficiency rates were about 25% in English language arts (ELA), 13% in math and 16% in science, compared with about 44%, 33% and 32%, respectively, at Oceanside Unified. The most important finding for families is that Jefferson’s results were below both district and state results in all three subjects.
There is no meaningful top-to-bottom school comparison because Jefferson is the only school in the list; it is therefore both the highest and lowest by default. Within the school, ELA had the highest all-grades result, while math was lowest. Science was closest to the state: Jefferson was 20 percentage points below California in science, compared with 24 points in ELA and 25 in math. Grade 7 ELA is a particular concern: 18% of students were proficient, 32 percentage points below the state result. Chronic absenteeism also stood out at 29%, versus 21% districtwide and 18% statewide.
Jefferson’s results improved in all three subjects from 2024–2025 to 2025–2026, and its gains exceeded the state’s in each: about 4 points in ELA, 3 in math and 7 in science, compared with less than 1, 1 and 3 points statewide. Even with those gains, the school remained below state proficiency levels. SchoolDigger placed Jefferson at the 11th percentile and gave it 1 star in 2025–2026. Other context includes an 18.5:1 student–teacher ratio in 2024–2025 and 93% free/reduced lunch eligible in 2024–2025; these figures alone do not explain test results. Because only one school is listed, the data cannot show how Jefferson compares with other local schools.
