Summary
Mount Baker Middle School in Mount Vernon, Washington, serves 569 students in grades 6–8. Located in the Mount Vernon School District, it serves a relatively high-need student population, with 70.83% of students qualifying for free or reduced-price lunch. The school has a student-teacher ratio of 18.7:1 and spent $18,362 per student in 2023–24. Its current statewide ranking is 492nd of 514 middle schools, approximately the 4th percentile, with a 0-star rating. The district ranks at approximately the 18th percentile statewide.
Academic results are well below district and state averages in every tested subject. In 2025–26, 21.56% of students were proficient in English language arts, 16.29% in math, and 12.43% in science. Science is the greatest concern: the result is nearly 19 percentage points below the district and fell sharply from 27.60% the previous year. Math has remained in the mid-to-high teens, while ELA has declined over four reported years. Seventh grade is a relative strength, especially in math, where 25.27% of students were proficient compared with 10.53% in grade 6 and 12.43% in grade 8. The school’s statewide ranking has also deteriorated, falling from approximately the 31st percentile in 2017–18 to the 4th percentile today.
The most useful comparison is nearby La Venture Middle School, just 1.22 miles away and in the same district. La Venture has a nearly identical free/reduced-price lunch rate, similar enrollment, spending, and student-teacher ratio, yet its 2025–26 proficiency rates were 42.30% in ELA, 34.39% in math, and 38.91% in science. Other nearby schools, including Anacortes Middle School, Port Susan Middle School, and Post Middle School, also report stronger results, though their student populations differ. Lincoln Academy results are suppressed because of its small enrollment and should not be interpreted as zero. Key issues for families and school leaders are science, grades 6 and 8 math, declining ELA performance, and understanding why La Venture is achieving stronger outcomes.
