Summary:
Deming, Washington, has one public high school, Mount Baker Senior High, serving grades 9–12. The school enrolls 513 students and is part of the Mount Baker School District. Because it is the only high school in the city, there is no local school-to-school comparison; the most useful comparisons are with the district and Washington state.
Mount Baker Senior High has a mixed but improving academic profile. Its strongest subject is English language arts, where 69.23% of students were proficient in 2025–26—about 16 percentage points above the state and 24 points above the district. Science proficiency was 52.53%, slightly higher than the statewide rate of 50.95%. Mathematics is the main weakness: 29.81% of students were proficient, nearly the same as the district but about 13 points below Washington’s rate. Still, all three subjects improved from the previous year, with math showing the largest gain, nearly 10 percentage points. The school’s reported ranking also improved substantially, moving from the 39th percentile to the 66th percentile and from a two-star to a three-star rating.
Parents should also consider student completion and school-support indicators. The reported graduation rate is 77.7%, below the statewide 82.6%, while the dropout rate is 17.0%, substantially higher than the state’s 9.8%. These results suggest that academic gains have not yet translated into equally strong graduation outcomes. The school has a 23:1 student–teacher ratio, and 48.54% of students receive free or reduced-price lunch, indicating that many students may benefit from additional academic, attendance, counseling, and persistence supports. Overall, the school shows encouraging momentum, especially in literacy and science, but families should ask about math intervention, credit recovery, attendance programs, and services for students at risk of leaving school before graduation.
