Summary:
ZIP code 92782 has three Legacy Magnet Academy, Heritage Elementary, and Peters Canyon Elementary, all in Tustin Unified. The two elementary schools serve elementary grades, while Legacy serves grades 6–12; together, they enroll 1,930 students. In 2025–2026, the schools’ average proficiency was 79% in ELA, 75% in math, and 74% in science, compared with state rates of 49%, 38%, and 36%. The area’s clearest strength is that all three schools exceeded the state rate in every tested subject, with school averages 29 to 38 points above state results.
Legacy had the highest all-grades ELA result at 84%, about 9 points above the average of the other schools, and narrowly led science at 77.4%, compared with 76.7% at Peters Canyon. Peters Canyon led math at 77%, about 3 points above the other schools’ average. Heritage had the lowest result in each subject—75% in ELA, 74% in math, and 68% in science—but still exceeded state rates by 26, 36, and 32 points, respectively. These all-grades results span different grade ranges; among the elementary schools, the leader varies by grade and subject.
Science showed the strongest recent improvement: Peters Canyon rose 16 points from the previous year, and the three-school average increased 8 points. Math also improved at all three schools, by 2 to 5 points, while the group’s ELA average was essentially unchanged. SchoolDigger rates all three schools five stars; its statewide rank history places Legacy at the 96th percentile, Heritage at the 93rd, and Peters Canyon at the 94th for 2025–2026. Other measures offer context, not a simple explanation for achievement: 2024–2025 free/reduced lunch eligible figures were 33% at Legacy and Heritage and 31% at Peters Canyon; student-teacher ratios were 26.2, 27.0, and 24.1, respectively. Chronic absenteeism was lowest at Legacy (5.5% at Heritage and 11.6% at Peters Canyon, versus 4.5% at Legacy), so Peters Canyon’s strong results coexist with the highest absenteeism rate.
