Summary:
Zip code 83655 contains one middle school, New Plymouth Middle School, which serves grades 6 through 8 with 225 students and is part of the New Plymouth District in Idaho. Since this is a single-school data set, the analysis focuses on how the school performs relative to its district and the state. New Plymouth Middle School has consistently ranked in the top quartile of Idaho middle schools, earning a 4-star rating with a rank of 39th out of 174 schools (78th percentile) in 2025-2026 and 21st out of 166 (87th percentile) the prior year.
The school's academic performance is strong across the board. In 2025-2026, math proficiency reached 56.8% and English language arts proficiency reached 63.1%, compared to state averages of 43.1% and 54.0% respectively. The school truly shines in 8th grade math, with a 70.5% proficiency rate versus the state's 41.2% — a gap of more than 29 percentage points. Science proficiency is also a strength, with 8th grade science at 56.4% versus the state's 42.9% in 2025-2026, and an even stronger 65.1% all-grades science proficiency in 2024-2025. Notably, the school shows an upward trend in both math and ELA from 6th to 8th grade, suggesting that students who remain through middle school tend to build stronger skills over time.
One area of concern is chronic absenteeism, which stands at 16.5% — notably higher than the district's 11.6% and the state's 13.8%. The school's economic context is relatively advantaged, with 37.33% of students qualifying for free or reduced-price lunch. The New Plymouth District is ranked 40th out of 101 Idaho districts with 3 stars, meaning the middle school's 4-star rating makes it a standout within an already above-average district. The only spending data available is from 2018-2019, showing $5,435 per student, so current resource comparisons are limited. While the school's statewide ranking dipped slightly in the most recent year, it remains a top academic performer and a strong choice for families in the 83655 area.
