Summary:
The 12 schools in Whittier City include 10 listed as elementary and two middle schools, with no high schools; Wallen L. Andrews and Whittier Independent Study serve students through grade 8. In 2025–26, the unweighted school averages were 48% in English language arts (ELA), 41% in math and 33% in science, compared with California averages of 49%, 38% and 36%. The gaps between the highest- and lowest-scoring schools were 33 points in ELA, 34 in math and 28 in science. Because schools serve different grade spans, these all-grades comparisons are broad snapshots; the main takeaway is that school-to-school differences are much larger than the area averages suggest.
Several schools stand out, but the leaders differ by subject. Wallen L. Andrews led ELA with 61%, ahead of Katherine Edwards at 58%; Orange Grove was lowest at 28%. In math, Daniel Phelan led at 60%, while Walter F. Dexter was lowest at 26%. Lydia Jackson led science at 47%, with Orange Grove lowest at 19%. Whittier Independent Study was also a strong performer in math and science, at 53% and 44%.
Average scores rose from 2024–25 to 2025–26 by about 1 point in ELA, 1 in math and 2 in science, but the state’s science average rose by 3 points, widening the area’s science gap. Whittier Independent Study had the largest increases in all three subjects, while Orange Grove fell in all three; SchoolDigger’s statewide percentile ranking for Dexter rose from 32nd to 44th. The reported free/reduced lunch eligible measure for 2024–25 ranged from 61% at Andrews to 89% at Lydia Jackson; these figures are context, not an explanation of scores. Student–teacher ratios ranged from 19.8 at West Whittier to 33.5 at Independent Study.
