Summary:
Zip code 83660 covers the Parma, Idaho area and contains just one public high school: Parma High School, which serves 305 students in grades 9–12 as part of the Parma District. The district is rated 4 stars and ranks 30th out of 101 Idaho districts, but Parma High School itself has consistently earned 3 stars while moving between the 52nd and 67th percentile in state rankings over the past few years.
Parma High School stands out most for its English Language Arts performance. In the 2024–2025 school year, 82.9% of students scored proficient in ELA on the ISAT, far exceeding both the district average of 54.2% and the state average of 53.9%. Science proficiency is also above state and district levels, with recent results showing 47–51% of students proficient compared to roughly 41–43% statewide. Chronic absenteeism is remarkably low at just 7.0%, about half the state rate of 13.8%, suggesting students are attending school consistently. However, math proficiency remains a clear weakness: only 28.6% of students were proficient on the end-of-course math exam in 2025–2026, below the 33.1% state average, and the 2024–2025 all-grades math result of 31.4% also lagged well behind the state’s 43.1%.
The school’s graduation rate is exactly at the state average of 82.5%, leaving room for improvement. About 46.6% of students qualify for free or reduced lunch, meaning Parma High School serves a notable share of low-income families, yet its strong attendance and literacy outcomes are positive signs. With a student-teacher ratio of 15.7:1 and spending of $9,393 per student (based on 2018–2019 data), the school has a typical resource level for an Idaho public high school. Overall, Parma High School offers a healthy learning environment with strong reading and science instruction, but boosting math proficiency and raising its graduation rate would likely help it move beyond its current 3-star rating.
