Summary:
There is exactly one high school in Heppner, Oregon: Heppner Junior/Senior High School, which serves grades 7–12 with 171 students and belongs to Morrow School District 1. Because it is the only school in the area, parents can look at how it compares with its district and the state. Its rank history has held steady at 4 stars for three years running: 43rd of 271 schools (84th percentile) in 2025–2026, 34th of 270 (87th percentile) in 2024–2025, and 69th of 268 (74th percentile) in 2023–2024. The district, by contrast, is rated 2 stars and ranks 74th of 141, at the 48th percentile.
The school's strongest results are in English Language Arts and Science. All-grade ELA proficiency is 65.9%, compared with 34.5% in the district and 43.8% statewide, while all-grade Science is 53.1%, versus 22.1% district and 30.6% state. Eleventh-grade results are especially high, at 75.0% in ELA and 62.5% in Science. It also posts a 100.0% graduation rate (district 96.7%, state 83.0%) and chronic absenteeism of 22.5%, better than both the district's 35.4% and the state's 33.5% — though roughly one in five students still misses school chronically.
Mathematics is the clear area to watch. All-grade math proficiency is 30.7%, above the district's 23.5% but 2.2 points below the state's 32.9%, and it is the only all-grade subject where the school trails the state. Seventh-grade math is a bright spot at 41.7% (state 33.3%), while 8th grade is 28.1% (state 30.0%) and 11th grade is 25.0% (state 22.9%) — meaning only one in four juniors is proficient. Note that with 171 students in grades 7–12, grade-level cohorts are small and percentages can swing on a few students. The school reports 66.67% free/reduced lunch participation, $28,115 per-student spending, and a 14.2 student-teacher ratio.
