Summary:

ZIP code 90731 has four high schools: three serving grades 9–12 and William J. Johnston Community Day serving grades 7–12; the group includes continuation and community day schools, so not all are directly comparable. Results vary sharply by school: in 2024–25, the gap between the highest and lowest results was 82 percentage points in English language arts (ELA), 38 in math, and 37 in science. The clearest takeaway is that a ZIP-code-wide picture hides major differences between schools.

Port of Los Angeles High led all three subjects in 2024–25, with 89% proficient in ELA, 44% in math, and 37% in science—above state results by 40, 7, and 4 points, respectively. Among schools with 2025–26 results, San Pedro Senior High led with 64% in ELA, 34% in math, and 45% in science; it was above the state in ELA and science but 5 points below in math. William J. Johnston Community Day had the lowest results in 2024–25 and reported 0% in all three subjects in 2025–26; Angel's Gate (Continuation) also had low results in 2024–25.

Results improved from 2024–25 to 2025–26 at San Pedro and Angel’s Gate: San Pedro rose 1 point in ELA, 5 in math, and 15 in science, while Angel’s Gate rose 4, 5, and 15 points. Johnston’s ELA and math results each fell 6 points, while science stayed at 0%. SchoolDigger rankings also place the schools far apart: San Pedro rose from the 64th to the 73rd percentile, Angel’s Gate from the 17th to the 25th, and Johnston fell from the 4th to the 1st; Port of Los Angeles High was at the 90th percentile in 2024–25. The reported 2024–25 free/reduced lunch eligible measure ranged from 64% at Port of Los Angeles High to 97% at Johnston, while student-teacher ratios ranged from 8.0 at Johnston to 20.4 at San Pedro; these are contextual observations, not explanations for results. Port of Los Angeles High has no supplied 2025–26 test results, and Johnston’s grade-specific results are suppressed.
