Summary:
Mosier, Oregon is a small city served by a single school, Mosier Community School, a K–8 school with 161 students that is classified as an elementary school but covers the middle grades, and there is no separate middle school, high school, or alternative school listed for the area. It belongs to North Wasco County School District 21, a district ranked 119th of 141 in Oregon, at the 16th percentile with 1 star.
Academically, the school outperforms its district in all-grade English Language Arts (38.3% vs. 30.5%), Mathematics (28.9% vs. 19.0%), and Science (22.6% vs. 20.6%), but trails the state in all three subjects, with the widest gap in science at 8.0 percentage points. Its statewide standing is stronger than its district's: the school sits at the 47th percentile with 2 stars in 2025–2026, up from the 40th percentile in 2023–2024 but down from the 57th percentile and 3 stars in 2024–2025. Grade-level results vary widely, with bright spots such as 4th grade math at 45.5% and 6th grade ELA at 47.8%, and weak spots including 7th grade math at 9.5%, 8th grade math at 16.7%, and 8th grade science at 16.7% — making middle-school math and science the clearest concern.
Context matters here: chronic absenteeism is 32.1%, lower than the district's 39.5% and the state's 33.5%, yet still about one in three students. The free/reduced lunch rate is 91.93%, per-student spending is $7,476, and the student-teacher ratio is 11.5. With only 161 students across K–8, single-grade percentages rest on small cohorts and should be read as directional rather than definitive.
