Zip code 83706 in Boise, Idaho, is served by 8 schools—5 elementary schools, 1 high school, and 2 alternative/charter schools—enrolling roughly 4,706 students in grades PK through 12, with no standalone middle school in the area.

Among elementary schools, Riverside Elementary School is the clear standout, ranking in the 89th percentile statewide with math and ELA proficiency of 69.6% and 73.3%, respectively. In contrast, Koelsch Elementary School and Garfield Elementary School rank near the bottom of Idaho (3rd and 5th percentile) with math proficiency below 22%. White Pine Elementary School and Liberty Elementary School fall in between but still beat state averages. At the secondary level, Sage International School Of Boise is the strongest option, with 58% math and 65.5% ELA proficiency, while Timberline High School—the only traditional high school—scores above the state in math and science but slightly below in ELA. Sage International School Middleton lags behind all of them, with proficiency below state averages in every subject.

Attendance and poverty closely track these outcomes. Koelsch Elementary School and Garfield Elementary School have free/reduced lunch rates above 95% and chronic absenteeism above 28%, while Riverside Elementary School has the lowest poverty rate (10.7%) and the lowest absenteeism (15.4%). Notably, Garfield spends the most per student ($13,098) yet has the lowest scores, while Riverside spends far less ($7,387) and achieves the best results; higher spending in high-poverty schools is common but does not guarantee higher achievement. Chronic absenteeism across every school with data exceeds the state rate of 13.8%. Timberline High School has also slipped from the 84th to the 67th percentile over the past two years, and with no middle schools in the zip code, families of grades 7–9 largely rely on the Sage charters or schools outside the area.
