Summary:
ZIP code 90027 has one listed high school, John Marshall Senior High, serving grades 9–12 and enrolling 1,842 students. Its results are not uniformly strong across subjects: in 2025–26, ELA proficiency was 70% and science was 46%, while math was 37.9%, slightly below California’s 38.4%. The clearest overall takeaway is that strong ELA results coexist with a notable chronic absenteeism concern.
There is no second school in the ZIP code to rank above or below John Marshall, but it stands out positively against state and district benchmarks in ELA and science. ELA proficiency was 20 percentage points above California and 21 points above Los Angeles Unified; science was 10 points above the state and 14 above the district. Math was close to the state result and 2 points below the district. Graduation was also higher than both benchmarks, at 95% versus 88% statewide and 90% districtwide, while the 3% dropout rate was below the state’s 8% and district’s 6%. Chronic absenteeism, however, was 32%, compared with 18% statewide and 23% districtwide.
Recent results improved in ELA and science but declined in math. From 2024–25 to 2025–26, John Marshall’s ELA proficiency rose 7 percentage points, compared with about half a point statewide, and science rose 7 points, compared with 3 statewide; math fell 4 points while the state gained 1. SchoolDigger placed the school in the 78th percentile in 2025–26, down from the 83rd percentile in 2023–24. Contextual figures include a student–teacher ratio of 19.3 and 71% free/reduced lunch eligible in 2024–25; these are observations, not explanations for results. Because the ZIP code has only one listed school, the data cannot show how its characteristics or results compare with another local school.
