Summary:
ZIP code 90222 has six elementary schools, serving grades from kindergarten through grade 6 or grade 8. In 2025–2026, the schools’ average math proficiency was 43%, above the state’s 38%, while their average ELA proficiency was 48% and science was 34%, both slightly below state results. Results vary considerably from one school to another, so the ZIP-code averages do not tell the whole story. The most important finding is the wide gap between the highest- and lowest-scoring schools: 41 percentage points in ELA, 47 in math and 42 in science.
Ronald E. McNair Elementary leads the group in all three subjects, with 64% proficiency in ELA, 62% in math and 60% in science. Jefferson Elementary ranks second in each, at 61%, 49% and 40%, respectively. At the other end, KIPP Compton Community scores 24% in ELA, 16% in math and 18% in science—the lowest results in the group in every subject. McNair is above state results in all three subjects; KIPP is below state results in all three.
Science improved most across the group: its average rose from 21% in 2024–2025 to 34% in 2025–2026, while the state rose from 33% to 36%. ELA and math averages each increased by about 1 percentage point, although the math advantage over the state narrowed slightly. SchoolDigger ranks McNair at the 80th percentile statewide and Jefferson at the 66th; those rankings are distinct from test scores. McNair’s student–teacher ratio is 23.8, while Jefferson’s is 27.2, showing that a higher ratio does not automatically mean lower results. For 2024–2025, reported free/reduced lunch eligible shares range from 76% at KIPP to 91% at Martin Luther King Elementary; these are contextual observations, not explanations for school outcomes.
