Summary:
Deming, Washington, has one middle school serving grades 7–8: Mount Baker Junior High, a small school with 244 students in the rural Mount Baker area. The school is part of the Mount Baker School District, so families looking for middle school options in Deming will find one local choice rather than multiple schools to compare.
Mount Baker Junior High has several encouraging signs. Student proficiency improved from the previous year in every reported subject: English Language Arts rose to 38.64%, math to 24.32%, and science to 29.25%. ELA is the school’s strongest area, while math is the weakest. Eighth graders also performed better than seventh graders in both ELA and math, with proficiency rates of 43% versus 35% in ELA and 26.21% versus 22.69% in math. Eighth-grade science performance was slightly higher than the district result, although the school’s overall science performance remained below state levels.
Parents should also be aware that the school continues to face academic challenges. Its 2025–2026 results were below both district and Washington averages in all-grade ELA, math, and science comparisons, with the largest statewide gap in science and the lowest proficiency in math. The school ranked at the 23rd percentile statewide and received a one-star rating, though this was an improvement from the 13th percentile the prior year. About 60.25% of students qualified for free or reduced-price lunch, and the student–teacher ratio was 17.6:1. Overall, the school shows broad recent improvement, but families may want to ask about math and science support, seventh-grade transition services, and how the school is continuing to build on its positive momentum.
