Middle Schools in North Wasco County School District 21

Middle schools in North Wasco County School District 21 consist of a single school: The Dalles Middle School, which serves grades 6–8 and enrolls 513 students at 1100 E 12th St in The Dalles. Because it is the only middle school in the district, there is no other school to compare it with; instead, its results can be compared against district and state averages. The district overall is ranked 119th of 141 in Oregon, at the 16th percentile, with 1 star.

Academically, the school's results are below Oregon averages in every tested subject. All-grade math proficiency is 16.4%, which is 16.5 percentage points below the state, and is the weakest area; the lowest single result is 6th grade math at 13.5%, meaning roughly 86.5% of 6th graders did not meet math proficiency. All-grade English language arts is the strongest subject at 31.0%, but still 12.8 points below the state, and grade-level ELA scores range from 28.2% to 33.1%, all below their state benchmarks. Science is 17.5% all-grade, 13.1 points below the state. The clearest relative bright spot is 7th grade math at 21.2% — the only grade-level subject score above its district comparison of 20.1%, though it remains 12.1 points below the state's 33.3%.

Other measures give useful context. Chronic absenteeism is 32.4%, better than the district's 39.5% and slightly better than the state's 33.5%, but still about one in three students. Free or reduced lunch enrollment is 99.03%, indicating near-universal economic disadvantage, while per-student spending is $17,667 and the student-teacher ratio is 17.1. Ranking history is persistently low: 1 star in each of the last three years, with percentile ranks of 19, 22, and 19, and 2024–2025 was the best of those years at 287 of 368.
