Summary:
The Nampa School District serves approximately 12,494 students across 20 schools in southwestern Idaho — 11 elementary schools, 3 middle schools, 5 high schools, and 1 alternative school — but the district is ranked just 85th out of 101 Idaho districts (16th percentile, 1 star). Parents will find wide variation in performance, with a few bright spots and several concerns. The district's biggest challenges are math proficiency, which trails the state average of 43.1% by roughly 12 points, and chronic absenteeism at 17.3% of students districtwide versus 13.8% statewide.
A few schools stand out for strong results. Lake Ridge Elementary is the highest-performing school in the district, with math proficiency of 46.5%, ELA of 51.9%, science of 51.0%, and a chronic absenteeism rate of just 2.7% — even though nearly half its students qualify for free/reduced lunch. Owyhee Elementary School also performs well, especially in ELA at 54.0%, matching the state average. South Middle School is the best middle school by far, outperforming East Valley Middle School and Lone Star Middle School in every subject; its 8th-grade science score of 43.5% exceeds the state average. Among high schools, Nampa Senior High School jumped from the 6th percentile to the 34th percentile in one year, while Columbia High School posted the district's best high school ELA score at 65.1%, above the state's 61.3%.
However, serious concerns remain. Math is the district's weakest subject at every level, with high school EOC scores ranging from 21.7% to 28.3% versus a state rate of 33.1%. Chronic absenteeism is especially problematic at Union High School (40.7%), Sherman Elementary (29.3%), and Lone Star Middle School (27.6%). Union High School also suffered a major ranking collapse, falling from the 58th to the 18th percentile despite the highest per-student spending in the district. Nampa Online Virtual Academy has the lowest test scores in the district (11.8% math, 26.6% ELA). The middle school years appear to be a critical transition point, with math proficiency declining from 6th to 8th grade at several schools, suggesting families should pay close attention to math support during this period.
