Madison Middle also beat the state average in 5th-grade science (45.4% vs. 44.0%) and exceeded the district's all-grades science proficiency (40.2% vs. 33.7%) in 2024–2025. Math is a weak point at both schools, though Madison Junior High (32.4%) outpaced Madison Middle (26.8%) in the most recent year, improving by 7 points while Madison Middle declined by nearly 5 points.

Madison Junior High's historical state rankings are very low (3rd percentile in 2022–2023 and 9th percentile in 2023–2024), although its most recent attendance and math results show improvement. Madison Middle has no state ranking history, but its science performance is a clear strength. For parents, these two schools are not interchangeable: Madison Middle is the stronger performer in English language arts and science, while Madison Junior High offers better attendance and improving math scores. Both schools remain below state averages in math and ELA, consistent with a district that is average for Idaho but showing a split personality between its lower and upper middle-grade campuses.
