Moscow Middle School is a standout performer, ranking 17th out of 174 Idaho middle schools — placing it in the 90th percentile with a 5-star rating. The school far exceeds state proficiency averages in every subject.

There are a few areas worth watching. Eighth-grade math proficiency was 63.4%, a notable 9.1-point drop from 7th grade's 72.5%, suggesting advanced coursework may be a challenge. The school also saw an ELA dip from 73.4% to 68.5% year over year. Chronic absenteeism stands at 17.3%, higher than both the district (16.6%) and state (13.8%) — a potential risk factor despite strong academic results. The school has also improved its state ranking over time, climbing from the 79th percentile in 2022–2023 to the 90th percentile in 2025–2026. With a low free/reduced lunch rate of 24.6%, the school serves a relatively low-poverty population, and its per-student spending is $11,134. Overall, Moscow Middle School is a high-achieving school with strong outcomes, but families should keep an eye on 8th-grade math and absenteeism.
