Summary:
Zip code 83350, serving the Rupert, Idaho area, is home to 2 middle schools that together educate 519 students in grades 6–8, both operating under the Minidoka County Joint District, a district that ranks 94th out of 101 Idaho school districts. The two schools differ sharply in size and purpose: East Minico Middle School enrolls 483 students as the area's primary comprehensive middle school, while Minidoka Junior High Alternative serves just 36 students in an alternative-program setting.
The differences in performance and climate are significant. East Minico has a chronic absenteeism rate of 9.4%, which is better than the district (14.5%) and state (13.8%) averages, while Minidoka Junior High Alternative struggles with a 42.6% chronic absenteeism rate — more than four times higher. Academically, East Minico's English language arts proficiency is 36.4%, compared to just 10.6% at the alternative school. East Minico also reports math proficiency of 24.6% and science proficiency of 20.4%, while Minidoka Junior High Alternative has no reported math or science data. Notably, the alternative school has a smaller student-teacher ratio (9.2 vs. 20.0) yet far weaker outcomes, and it also serves a higher poverty population, with 80.56% of students qualifying for free/reduced lunch versus 61.08% at East Minico.
Both schools fall well below Idaho state averages, where 43.1% of students are proficient in math, 54.0% in ELA, and 42.6% in science. East Minico's 6th-grade ELA proficiency of 37.6% does surpass the district average of 32.7%, offering a relative bright spot in an otherwise challenging picture. However, East Minico's scores are edging downward, with math proficiency slipping from 27.6% to 24.6% between 2024–2025 and 2025–2026. The most urgent concerns center on Minidoka Junior High Alternative, where extreme absenteeism and very low ELA proficiency signal a high-need student population requiring immediate intervention.
