Summary:
Zip code 95304 has one middle school, Jefferson, serving grades 5–8 and enrolling 388 students, so there is no other local middle school to compare it with. In 2025–2026, its all-grades proficiency was above the state in ELA (67% versus 49%), math (63% versus 38%) and science (55% versus 36%). The most important counterpoint is the reported chronic-absenteeism measure: 92% at Jefferson, compared with 21% in the Jefferson Elementary district and 18% statewide.
Jefferson is the only school in this ZIP-code sample, rather than a local leader or laggard among multiple schools. Math is its strongest subject against the state: the 25-point advantage exceeds its 19-point science and 17-point ELA advantages. Science is a relative weak spot against its district: Jefferson was 1 point below the district, while its ELA and math results were 5 and 6 points higher. Grade-level results show a particularly strong point in grade 6 math, where 75% were proficient, 37 points above the state and 14 above the district. ELA results were not as uniformly ahead of the district: Jefferson was 1 point lower in grade 5 and 3 points lower in grade 8.
Test results remain above state levels, but Jefferson’s proficiency fell from 2024–2025 to 2025–2026 by 8 points in ELA, 8 in math and 11 in science; its state advantages narrowed by 8, 10 and 15 points, respectively. SchoolDigger still gives the school 5 stars and ranks it 261 of 2,703, in the 90th percentile, though its rank was 103 of 2,783 in 2023–2024. Its 2024–2025 student–teacher ratio was 22.2:1, and 26% of students were free/reduced lunch eligible that year. These are useful context about the sole school, but do not allow comparisons across schools in the ZIP code.
