Schools in Zip Code 83629

Zip code 83629, in Horseshoe Bend, Idaho, is served by two very small public schools within the Horseshoe Bend School District: Horseshoe Bend Elementary (PK–5, 84 students) and Horseshoe Bend Middle/Senior High (grades 6–12, 86 students). The two schools share a campus and split enrollment nearly evenly at 170 total students. Both serve mostly low-income families, with free/reduced lunch rates of 58.3% at the elementary and 52.3% at the high school.

Horseshoe Bend Elementary is the clear academic standout, with 2025–2026 math proficiency of 45.0% that beat both the district (30.2%) and state (43.1%), and ELA at 47.5% — well above the district's 38.4% and near the state's 54.0%. It also gained 16.7 points in ELA year over year. Horseshoe Bend Middle/Senior High, meanwhile, saw math proficiency collapse from 45.5% to 17.4% in a single year, with ELA at 30.4%. The elementary school achieves these better results despite a higher poverty rate, indicating the high school's problems are not purely economic.

Absenteeism may be a factor, as the high school's chronic absenteeism rate (19.0%) exceeds the elementary school's (13.9%) and the state's (13.8%). The high school also spends less per student ($11,547 versus $12,803) despite having a lower student–teacher ratio (7.8 versus 13.2). With only about 12–13 students per grade in the high school and 14 at the elementary school, a handful of students can shift proficiency rates dramatically. The high school's 82.5% graduation rate exactly matches district and state figures, likely reflecting its small size. Overall, the district's low combined math score is driven primarily by the high school, while the elementary school demonstrates that strong results are achievable in this community.
