Summary
Evergreen Elementary serves 709 students in grades K–5 in Diamond Bar, California, and is part of Walnut Valley Unified. Its test results are strong compared with California overall, but the most important finding is that all three subject results are below district averages: by 7 percentage points in English language arts (ELA), 5 in math and 2 in science.
Compared with the state, Evergreen is ahead by 20 points in ELA, 30 in math and 26 in science, with proficiency rates of 69%, 68% and 62%, respectively. Among the 10 nearby schools in the supplied comparison, it ranks fifth in ELA, fifth in math and fourth in science. Its relative strength is science: its 62% result is close to the 62% average for the other nearby schools in its district. Math is its biggest district shortfall. There is also a grade-level concern: fourth-grade math is 63%, compared with 73% districtwide, and is the lowest among the seven district schools listed. Fifth-grade ELA is a brighter spot at 76%, above the district’s 74%.
Results have declined since 2022–2023: ELA is down 4 points, math 2 and science 3, even as state results rose. Attendance offers a positive contrast: chronic absenteeism was 3% in 2025–2026, below the district’s 6% and state’s 18%. SchoolDigger rates Evergreen 4 stars, ranking it 698 of 5,804 California schools, at the 88th percentile; its percentile has fallen from 93 in 2023–2024. A notable subgroup finding is that SchoolDigger’s statewide measure for how well the school serves Asian students is at the 45th percentile (rank 664 of 1,207, 2 stars), compared with 88th overall. For context, the 2024–2025 free/reduced lunch eligible measure was 26%, and the student-teacher ratio was 24.9. These are descriptive measures, not explanations for test results.
