Summary:
Zip code 90220 has seven Compton Unified elementary schools, all serving kindergarten through eighth grade. Across the group, average proficiency in 2025–2026 was 48% in math and 52% in English language arts (ELA), above state averages of 38% and 49%; science averaged 33%, below the state’s 36%. Chronic absenteeism was low across the schools, averaging 4%, compared with 13% in the district and 18% statewide. The key takeaway is that the area’s average results look strongest in math, but school-to-school differences—especially in math—make individual school results more useful than the neighborhood average alone.
Laurel Street leads across all three subjects, with 64% proficiency in ELA, 64% in math and 45% in science; it is above the state in each. Tibby is close behind in ELA and math, at 63% in each, while Longfellow stands out for recent gains. At the lower end, McKinley has the lowest math and science results, at 32% and 25%, and ELA of 42%; Bursch has the lowest ELA, at 41%, but its math result is higher, at 44%. The widest school-to-school spread is in math: 33 percentage points between Laurel Street and McKinley.
Results rose in all three subjects on average from 2024–2025 to 2025–2026, with the biggest change in science: the group average increased by 15 percentage points, compared with 4 points in math and almost no change in ELA. Longfellow improved in all subjects, including 16 points in math, while science increased at every school. SchoolDigger ranks Laurel Street at the 86th statewide percentile and Longfellow at the 62nd, up from the 30th percentile in 2023–2024; Tibby’s rank went from the 76th to the 67th percentile. Tibby’s grade-level results also vary: seventh-grade proficiency is 100% in ELA and 98% in math, while fifth-grade math is 33% and science 22%. All schools report free/reduced lunch eligible for 2024–2025, ranging from 85% to 92%, and their student-teacher ratios range from 22.5 to 25.4; these figures do not show a simple pattern alongside achievement.
