Summary:
ZIP code 92603 includes four elementary schools in Irvine Unified: three serve kindergarten through grade 6, while Vista Verde serves through grade 8. Together they enroll 2,883 students, with school sizes ranging from 395 to 881. In 2025–2026, the four-school average was 78% in ELA, 76% in math and 72% in science—about 29, 37 and 36 percentage points above state results, respectively. Still, the most important finding is that all four schools exceed state results in every subject, while performance varies substantially among the local schools.
The leaders differ by subject: Bonita Canyon Elementary leads all-grades ELA at 82%, Vista Verde leads math at 81%, and Turtle Rock Elementary leads science at 83%—11 percentage points above the next-highest school. Alderwood Elementary is lowest in all three subjects, at 70% in ELA, 60% in math and 66% in science. Compared with the average of the other three schools, Alderwood trails by 11 points in ELA, 21 in math and 8 in science. Grade-level leaders can differ from all-grades leaders, too: Bonita Canyon leads ELA and math in grades 3, 4 and 6, while Turtle Rock leads both subjects in grade 5.
The group’s advantage over the state narrowed from 2024–2025 to 2025–2026 by about 2 percentage points in ELA, 2 in math and 4 in science. Individual science results moved in opposite directions: Turtle Rock rose 9 points, while Vista Verde and Bonita Canyon each fell about 9. SchoolDigger awards five stars to Turtle Rock, Vista Verde and Bonita Canyon, and four to Alderwood. Context measures also vary: student-teacher ratios range from 26.3 at Bonita Canyon to 30.7 at Turtle Rock; reported free/reduced lunch eligible shares for 2024–2025 range from 10% at Vista Verde to 26% at Alderwood. Vista Verde’s K–8 span means its all-grades results cover different grades from the other schools, so grade-level results are useful for closer comparisons.
