Best Public Schools in Boise, ID

Boise, Idaho, is home to 76 schools serving students from elementary through high school: 50 elementary schools, 10 middle schools, 13 high schools, and 3 alternative schools, led by Joint School District No. 2 and Boise Independent District. Boise's standout elementary schools are exceptional, with Collister Elementary School, Longfellow Elementary School, Adams Elementary School, and Summerwind STEM Academy ranking in Idaho's top 5% with math proficiency between 73% and 78%, far above the state average of 43.1%. At the middle school level, East Junior High School, Lowell Scott Middle School, North Junior High School, and Les Bois Junior High School all rank above the 80th percentile statewide, while Centennial High School stands out among high schools with a #24 state ranking and the lowest chronic absenteeism among comprehensive high schools.

The contrasts across Boise are stark. Centennial High School and Timberline High School clearly outperform Boise Senior High School, Borah Senior High School, and Capital Senior High School, and the pattern tracks closely with chronic absenteeism: Capital Senior High School has 30.8% chronic absenteeism and the lowest test scores, while Centennial High School has the best attendance and scores. Among alternative and charter options, Sage International School of Boise is a strong performer with proficiency well above state averages, but virtual schools are consistently the lowest-performing, with iSucceed Academy ranked dead last in Idaho, and iSUCCEED Virtual High School, Empower Connections Academy, and Boise Online School - Secondary all posting math proficiency below 15%.

Two key takeaways are the strong relationship between poverty and proficiency, and the weak relationship between spending and outcomes. High-poverty schools like Whittier Elementary School, Koelsch Elementary School, and Morley Nelson Elementary score in the 16-34% proficiency range, yet Hawthorne Elementary School and Monroe Elementary School both exceed 50% proficiency despite nearly 98% free/reduced lunch eligibility, showing poverty need not determine outcomes. Meanwhile, Frank Church High School spends the most per student ($16,964) yet posts low proficiency rates, while top performers like Pioneer School of the Arts and Centennial High School spend under $7,000 per student, suggesting parents should examine individual school data rather than district rankings.
