Summary

Wilson Elementary serves 544 students in grades 2–5 in Gridley, California. In 2025–2026, its proficiency rates were below California’s in English language arts (ELA), math and science. The clearest concern is math: Wilson’s 28% proficiency was 10 points below the state.

Compared with six nearby schools that reported all-grades results, Wilson ranked fourth in ELA, fifth in math and third in science; nearby averages were 45% in ELA, 44% in math and 27% in science, versus Wilson’s 41%, 28% and 28%. Science is a relative bright spot locally: Wilson had the highest reported grade 5 science result among nearby schools, at 28%, though it was still 8 points below the state’s 36%. Wilson was also below Gridley Unified in all three subjects: by 7 points in ELA, 1 point in math and 3 points in science. Nearby schools serve different grade spans, so all-grades comparisons are not fully like-for-like.

Wilson’s results and SchoolDigger standing have weakened recently. Its all-grades math proficiency fell from 38% in 2022–2023 to 28% in 2025–2026, and its SchoolDigger statewide percentile declined from 58 in 2023–2024 to 38 in 2025–2026; its rating also fell from 3 stars to 2. SchoolDigger’s percentile for Hispanic Students dropped from 65 to 31 over those years, a 34-point decline in its assessment of how well the school serves that group. In 2025–2026, its White Students percentile was 20, compared with 38 overall. Wilson’s 2024–2025 student–teacher ratio was 22.6, the highest among nearby schools with reported ratios that year. Its reported free/reduced lunch eligible rate was 80% in 2024–2025, the fifth-highest among ten nearby schools reporting that measure.
