Summary:

Wilmar Union Elementary has one listed school, Wilson Elementary, which serves grades K–6 and has 235 students and a student–teacher ratio of 23.4. With only one school in the list, there is no meaningful local school-to-school comparison. Most importantly, in 2025–2026 Wilson’s all-grade proficiency rates were above the state’s in ELA, math, and science.

Wilson Elementary is both the top and bottom school in this one-school list; the more useful differences are across grades. Its all-grade results exceeded state rates by 3 points in ELA (52% versus 49%), 8 points in math (46% versus 38%), and 6 points in science (42% versus 36%). Fifth grade was a particular strength: ELA was 15 points above the state, math 6 points above, and science 7 points above. The main exception was sixth-grade ELA, 10 points below the state (38% versus 48%); third-grade math was also 2 points below (45% versus 47%).

Results changed unevenly from 2024–2025 to 2025–2026: Wilson Elementary fell 2 points in ELA and 5 in math, but rose 4 points in science. Its average advantage over the state across the three subjects narrowed from 8 points to 6, even as the ELA and math gaps shrank and the science gap widened. SchoolDigger’s ranking moved from 851 of 5,869 schools (86th percentile) in 2023–2024 to 1,976 of 5,804 (66th percentile) in 2025–2026, and its rating went from 4 stars to 3. Context measures show 20% free/reduced lunch eligible in 2024–2025 and chronic absenteeism of 8% in 2025–2026, matching the district and below the state’s 18%.
