Summary

Del Rey Elementary is a 373-student K–5 school in San Lorenzo Unified, serving families in San Lorenzo alongside several nearby elementary schools. In 2025–26, 28% of students were proficient in English Language Arts (ELA), 30% in math, and 22% in science. The most important concern is that Del Rey scored below California in all three subjects, and its state-level gaps have widened since 2022–23.

Math is Del Rey’s clearest relative strength: its 30% proficiency was 7 percentage points above the district and 9 points below the state. ELA was its weakest comparison, at 28%—about even with the district but 21 points below the state. Science proficiency was 22%, 1 point above the district and 14 below the state. Among nine nearby K–5 schools with comparable results, Del Rey ranked fourth in math and science and fifth in ELA. Grade-level results show another bright spot: fourth graders reached 37% in ELA and 38% in math, while fifth-grade math was just 20%, below both the district and state.

Results over time are mixed: from 2022–23 to 2025–26, Del Rey’s state gaps widened by 8 points in ELA, 7 in math, and 6 in science; ELA proficiency fell by 5 points and math by 3, while science was nearly unchanged. SchoolDigger ranks Del Rey in the 26th percentile statewide, with 1 star, down from the 41st percentile in 2022–23 and 2023–24. Its student-teacher ratio was 23.3 in 2024–25, among the highest of nearby K–5 schools. In that same school year, 69% of students were free/reduced lunch eligible. Chronic absenteeism improved from 51% in 2021–22 to 23% in 2025–26, though the latest rate remained above the state’s 18%. One subgroup result stands out: SchoolDigger placed Low Socio Economic Status Students in the 6th percentile in 2025–26, down from the 27th percentile two years earlier, compared with the school’s overall 26th percentile.
