Summary:
Zip code 83686 in Nampa, Idaho is home to seven elementary schools: six traditional public schools in the Nampa School District serving grades PK-5, plus one public charter school, Legacy Charter School, which serves grades K-8. Enrollment ranges from 311 students at Legacy Charter to 586 at Reagan Elementary School, and the data shows a striking academic divide within this single zip code.
Legacy Charter School is the clear standout, ranking 22nd out of 346 Idaho elementary schools (94th percentile) with 73.7% math and 83.4% ELA proficiency - roughly 35-38 percentage points above the district schools in this zip code. Among the traditional district schools, Lake Ridge Elementary is the best performer, ranking 179th (48th percentile) with math proficiency above the state average and very low chronic absenteeism of 2.7%. Owyhee Elementary School is the most balanced, matching the state average in ELA. At the other end, Sherman Elementary ranks 319th (8th percentile) with the lowest test scores and highest chronic absenteeism (29.3%) despite spending the most per student ($8,277).
Chronic absenteeism tracks strongly with performance: the top schools (Legacy Charter School at 2.3% and Lake Ridge Elementary at 2.7%) have dramatically better attendance than the bottom schools (Sherman Elementary at 29.3% and Iowa Elementary at 27.7%). Spending per student does not predict outcomes - Sherman spends the most yet scores the lowest, while Legacy Charter School spends moderately and achieves the best results. Free/reduced lunch rates are high across nearly all schools, ranging from 29.6% at Legacy Charter School to 68% at Iowa Elementary, yet poverty alone does not explain the divide. A common weak spot is 4th-grade math, with several schools showing sharp drops from 3rd to 4th grade. For parents, the clearest takeaway is that improving attendance - particularly at Iowa Elementary, Sherman Elementary, and Roosevelt Elementary School - could be one of the most effective strategies for raising achievement in this zip code.
