From 2022–2023 to 2025–2026, science rose from 35% to 43%, increasing its state advantage from 5 to 7 points. ELA fell from 64% to 55%, narrowing its state lead from 18 to 6 points; math stayed near 29% as the state improved, widening Harbor’s deficit from 6 to 9 points. Chronic absenteeism has improved from 26% in 2021–2022 to 20% in 2025–2026, but remains above state and district rates. The student–teacher ratio was 18.5 in 2024–2025, compared with a nearby-school average of 19.6; 38% of students were free/reduced lunch eligible that year, a measure distinct from California’s Community Eligibility provision of free meals for all students. SchoolDigger’s subgroup standings show a notable swing for Special Education Students: the group ranked at the 76th percentile in 2025–2026, up from 28 the prior year. Multi-racial Students ranked at the 42nd percentile, below the school’s overall 66th-percentile standing.
