Summary
Nyssa High School is a public school serving grades 9–12 with 335 students in the high-poverty community of Nyssa, Oregon, part of Nyssa School District 26. The district ranks 27th of 141 Oregon districts (81st percentile, 4 stars), but the high school’s latest statewide rank is 155th of 271 (43rd percentile, 2 stars) in 2025–2026—a sharp drop from 39th of 270 (86th percentile, 4 stars) the year before. About 91.64% of students qualify for free or reduced lunch, and the 2024–2025 graduation rate is 94.0%, above the district (86.7%) and state (83.0%). Chronic absenteeism is 28.0%, below the state (33.5%) but above the district (10.6%).
Compared with nearby schools, Nyssa is mid-sized between Vale High School (293 students), Ontario High School (709), and Adrian High School (83). Nyssa spends less per student ($20,490) than all three, but its 14.4 student-teacher ratio is better than Vale’s 15 and Ontario’s 17.7. In 2025–2026 11th-grade ELA, Nyssa’s 45.6% is near the state average (46.0%), below Vale (79.7%) and Adrian (58.3%), and above Ontario (27.7%). Math is the clear weak point: 16.2% proficient, below the state (22.9%), Vale (43.5%), and Adrian (25%), though above Ontario’s “under 5%.” Science is 30.4%, below the state (33.8%) but second among the four nearby schools. Graduation is 94.0%, above Ontario (88.8%) but below Vale (98.4%) and Adrian (100.0%), while chronic absenteeism of 28.0% is higher than every nearby school—Vale 11.1%, Adrian 21.8%, Ontario 26.6%.
Nyssa High School and Vale High School serve almost identical free/reduced-lunch populations (91.64% vs. 90.44%), yet Vale outperforms Nyssa in ELA, math, science, graduation, and absenteeism, suggesting poverty alone does not explain the gap. Nyssa School District 26 is stronger than its high school right now, and the latest rank decline was not evenly distributed: some student groups remained high-performing, but low-income, male, and female student groups all fell sharply. The bottom line: Nyssa has a strong graduation rate, near-state ELA, and relatively solid science compared with nearby peers, but its most urgent challenges are very low math proficiency, chronic absenteeism higher than all nearby schools, and widening gaps for some student groups.
