Summary:
ZIP code 98520, which includes the Aberdeen area, has one listed middle school: Miller Junior High, serving grades 6–8 and enrolling 656 students. Because it is the only middle school in the ZIP code, parents cannot compare it with another nearby school within the same ZIP. The school is part of Aberdeen School District, which ranks near the lower end of Washington districts. About 70% of students qualify for free or reduced-price lunch, and the student–teacher ratio is 20.1 to 1, providing important context about the community and the level of support many students may need.
Academic results at Miller Junior High are below Washington averages, especially in mathematics. In 2025–2026, approximately 31% of students were proficient in English language arts, 15% in math, and 32% in science, compared with statewide rates of about 53%, 43%, and 51%. Math is the clearest area of concern across all three grades. Still, the school generally performed close to or slightly above district averages in grade-level comparisons: it exceeded district math results in grades 6, 7, and 8, and was at or above district ELA results in each grade. Seventh grade was the strongest ELA grade, while eighth grade had the highest math performance.
There are also some encouraging trends. Science proficiency rose by about 8 percentage points from the prior year, while ELA improved slightly; math was nearly unchanged. The school’s statewide ranking improved in the latest year, although it remained around the 11th percentile, indicating that significant challenges persist. For families considering this school, the most important takeaway is that Miller Junior High shows some progress and performs competitively with its district in several grade-level measures, but its overall achievement—particularly in math—remains substantially below state results.
