Summary

Sumner Elementary serves 444 students in kindergarten through grade 6 in Claremont, within Claremont Unified, and is surrounded by elementary schools in Claremont and nearby communities. Its 2025–2026 test results are above California’s in English language arts (ELA), math, and science, but below the district in all three; the most important takeaway is that Sumner’s state-level advantage comes alongside a substantial gap with its district and most nearby schools.

Sumner’s results are among the lower ones locally, especially in math and science. In 2025–2026, ELA was 55%, math 48%, and science 36%—above state results of 49%, 38%, and 36%, respectively, but below Claremont Unified at 64%, 54%, and 53%. Among nine nearby schools with reported results, Sumner ranked second-lowest in ELA and math and third-lowest in science. It was also second-lowest in ELA and lowest in math among the five same-district K–6 schools. Mountain View Elementary had slightly higher ELA and math results, while its science result was slightly lower than Sumner’s.

ELA has improved most over time: from 2022–2023 to 2025–2026, Sumner rose 11 points, from 44% to 55%; math rose 4 points, while science fell 5 points, from 41% to 36%. SchoolDigger ranks Sumner 1,790th of 5,804 schools, at the 69th percentile with 3 stars—about the same percentile as Mountain View, but below most other rated nearby schools. In 2024–2025, its student–teacher ratio was 23.3, below the nearby general-school average of 24.4; its free/reduced lunch eligible measure was 46%. SchoolDigger’s statewide effectiveness ranking for Hispanic students was notably higher than Sumner’s overall standing, at the 87th percentile in 2025–2026, up from the 57th percentile two years earlier. Its ranking for White students was lower, at the 35th percentile that year.
