Summary:
ZIP code 98816 has one listed middle school serving grades 6–8: Chelan Middle School, part of the Lake Chelan School District. The school enrolls 285 students and serves an area where 61.4% of students qualified for free or reduced-price meals in 2024–25. With no other middle school in the ZIP code for comparison, the most useful view is the school’s progress over time and its results compared with district and Washington averages.
Chelan Middle School has shown strong overall momentum. Its statewide ranking improved from the 43rd percentile in 2023–24 to the 70th percentile in 2025–26, while its rating increased from two stars to four. In 2025–26, 57.25% of students were proficient in English language arts, compared with 52.81% statewide, and 49.62% were proficient in math, compared with 43.11% statewide. The school also exceeded district results in both subjects. Math was the biggest recent success, improving by 7.55 percentage points in one year. Sixth grade was especially strong, with 64.37% proficiency in ELA and 63.22% in math. However, seventh-grade math was much lower at 40.63%, suggesting that the transition into seventh grade deserves attention.
Science is the clearest area for improvement. Only 40.51% of students were proficient in science in 2025–26, compared with 50.95% statewide and 41.98% districtwide. Science did improve modestly from the previous year, but the gap with Washington remained large. ELA was essentially steady year over year, while math made substantial gains. The reported student-teacher ratio is 13.7:1, and per-student spending was $18,611 in 2023–24, although these figures cannot be judged without comparable local data. For families considering the school, the main positives are its improving ranking, above-state ELA and math results, and strong sixth-grade performance; the main questions are how the school supports seventh-grade math and what plans are in place to strengthen science.
