Understanding the 1/10 Rating
SchoolDistrictFinder rates Minidoka County Joint School District 331 1 out of 10 — low-rated among Idaho public school districts. Our ratings are based on state assessment results — the share of students scoring proficient or above in reading and math, as reported in the U.S. Department of Education’s EDFacts collection (2021–22 school year). We average each district’s reading and math proficiency, then rank it against other districts in the same state to produce a 1–10 score. Because Idaho is compared only against itself, the rating reflects how this district performs relative to its in-state peers.
Minidoka County Joint School District 331 holds a low overall rating, with reading and math proficiency among the lowest in Idaho on state assessments. Test results reflect many factors beyond the classroom, including community and economic conditions; a low score is a signal to research carefully, not a verdict on any individual school or teacher. Families in this area should research all available alternatives: inter-district transfers, charter schools, and magnet programs. Contact the district directly to understand exactly what programs are available at your assigned school.
