Summary:
ZIP code 97040 covers Mosier, Oregon, and contains exactly one public school: Mosier Community School, a K–8 school with 161 students in North Wasco County School District 21. It is the only school in the ZIP, so it serves as both the elementary and middle school for the community, and there are no middle, high, or alternative schools nearby. Note also that the data is a snapshot with mixed years: test scores are for 2025–2026, while absenteeism, free/reduced lunch, spending, and student–teacher ratio are for 2024–2025.
The school's clearest pattern is that it outperforms its own district but trails the state. At the all-grades level it beats North Wasco County School District 21 in English language arts (38.3% vs. 30.5%), math (28.9% vs. 19.0%), and science (22.6% vs. 20.6%), yet sits below Oregon in all three (43.8%, 32.9%, and 30.6%). It also outperforms its district in 12 of 14 grade-level subject comparisons. The school earned 2 stars and a 47th-percentile rank (373 of 709), while the district sits at 1 star and the 16th percentile (119 of 141). Its genuine strengths include 4th-grade math at 45.5% (6.6 points above the state), 6th-grade ELA at 47.8% (6.0 points above), and 8th-grade ELA at 41.7%, essentially at state parity.
Weaknesses concentrate in upper-grade math and in science. Grade 7 math is just 9.5% proficient — 23.8 points below the state and 10.6 points below the school's own district — and grade 8 math (16.7%) is 13.3 points below the state. Science is 8.0 points behind the state overall, with 8th-grade science at 16.7%, 11 points below state. Chronic absenteeism, at 32.1%, is lower than both the district (39.5%) and the state (33.5%), which is notable given that 91.93% of students qualify for free/reduced lunch. The school reports $7,476 per student and an 11.5:1 student–teacher ratio. Because roughly 18 students sit in each grade, a single student can shift a grade's percentage by several points, so the all-grades figures are the most reliable.
