High Schools in ABC Unified

The six high schools in ABC Unified include conventional high schools serving grades 9–12, a continuation school, a grades 7–12 school, and an alternative school. Five report 2025–2026 proficiency results; ABC Secondary (Alternative) has no supplied test scores. The defining finding is how sharply results vary by school: the range between the highest- and lowest-scoring schools is 84 percentage points in ELA, 96 in math, and 92 in science.

Whitney (Gretchen) High leads all three subjects, with 99% proficiency in ELA, 99% in math, and 98% in science—about 50, 61, and 62 points above state results. Its 11th-grade results are also exceptional: 99% in ELA, 100% in math, and 96% in science. At the other end, Tracy (Wilbur) High (Continuation) reports 15% in ELA, 3% in math, and 5% in science, below state results in every subject. Cerritos High leads the other conventional high schools, ahead of Gahr (Richard) High and Artesia High in all three subjects; Artesia is below state results in math and science.

Recent trends separate these schools further: Gahr gained about 10–11 points in each subject from 2024–2025, while Cerritos fell about 10 points in ELA and science and 14 in math; Artesia improved, and Tracy declined. SchoolDigger ranked Whitney 4th of 2,137 schools in 2025–2026, after ranking it 1st in each of the two prior years shown. Income figures provide context, not an explanation: in 2024–2025, free/reduced lunch eligible shares were 86% at Artesia, 61% at Gahr, 43% at Cerritos, and 31% at Whitney. Graduation and attendance also tell different stories: conventional high schools had graduation rates of 98%–100%, while chronic absenteeism ranged from 5% at Whitney to 72% at Tracy.
