Summary:
ZIP code 97913 contains a single high school, Nyssa High School, which serves grades 9–12 with 335 students as part of Nyssa School District 26 in a small, rural Eastern Oregon community. Because it is the only high school in this ZIP code, there are no local peer schools to compare it against; the most useful comparisons are to the district and to Oregon statewide averages.
The school's strongest results are in graduation and English language arts. Its graduation rate is 94.0%, which is above both the district (86.7%) and state (83.0%) rates. ELA proficiency is 45.6%, slightly above the state all-grades average of 43.8% and close to the district's 46.8%, while science proficiency is 30.4%, essentially matching the state average of 30.6%. Chronic absenteeism is 28.0%, which is lower than Oregon's 33.5% but well above the district's 10.6%, suggesting attendance is a more localized challenge at the high school level. About 91.64% of students qualify for free or reduced lunch, and per-student spending is $20,490, with a student-teacher ratio of 14.4.
The clearest area of concern is mathematics. Only 16.2% of students are proficient in math, roughly half the state all-grades rate of 32.9% and far below the district's 32.8% — a 29.4 percentage-point gap behind ELA within the same school. At the 11th-grade level the school and district both show 16.2% math proficiency versus 22.9% statewide, while the district's all-grades math rate is higher, implying younger grades perform better in math. The school's rating has also swung sharply: 3 stars in 2023–2024, 4 stars in 2024–2025, and 2 stars in 2025–2026, when it ranked 155th of 271 high schools at the 43rd percentile. Meanwhile the district overall ranks 27th of 141 at the 81st percentile with 4 stars. For families, the takeaway is strong graduation and ELA outcomes, with math as the priority for improvement.
