From 2024–2025 to 2025–2026, Buhach Colony math proficiency rose 10 points, while Atwater science rose 6 points; Atwater ELA slipped 1 point. The two-school math average improved, narrowing its gap with the state from 23 to 18 points, while the ELA gap widened slightly and the science gap was essentially unchanged. As context, Atwater has a lower student-teacher ratio (20.6 versus 22.5) and a higher share reported as free/reduced lunch eligible in 2024–2025 (82% versus 79%); these differences do not explain the test results. SchoolDigger rankings also show contrasting longer-term movement: Buhach Colony rose from the 39th to 55th percentile over three years, while Atwater moved from the 40th to 37th.
