New Plymouth High School

New Plymouth High School serves 269 students in grades 9–12 in the agricultural community of New Plymouth, Idaho, a small town in the western part of the state near the Oregon border.

The school is part of the New Plymouth District, which earned a 3-star rating and ranks 40th out of 101 Idaho districts. The high school itself received a 2-star rating for 2025–2026, ranking 67th out of 122 Idaho high schools—an improvement from the previous year but well below its 4-star peak in 2012–2013. One of the school's clearest strengths is attendance: its chronic absenteeism rate is just 8.8%, far below the state rate of 13.8%. The school also serves a comparatively less economically disadvantaged population than its neighbors, with only 28.62% of students eligible for free or reduced-price lunch, the lowest among nearby traditional high schools.

Academically, New Plymouth High School's performance is mixed. On the most recent End-of-Course ISAT, 57.8% of students were proficient in English Language Arts, and 34.4% were proficient in math—close to state averages—but science proficiency lagged at 40.6%. The graduation rate, historically strong, slipped to 82.5% in 2024–2025, now exactly at the state average. Comparisons with nearby schools are revealing: Parma High School, despite a much higher poverty rate (46.56%), outperformed New Plymouth High School in ELA (82.9% vs. 58.5%) and science (51.4% vs. 28.3%) on the 2024–2025 All-Grades ISAT. Emmett High School also posted higher ELA proficiency while serving a larger, more economically diverse student body. For parents, New Plymouth High School offers a well-attended environment with solid ELA results, but math and science—along with the recent graduation dip—are areas worth watching closely.
