Summary:
Sumner, Washington, has five public schools serving about 4,198 students from elementary through high school, all within the Sumner-Bonney Lake School District, a highly ranked district in the state. The area includes three elementary schools, one middle school, and one high school. Overall performance is strong, but results vary considerably by school and subject.
Maple Lawn Elementary is the clear standout, ranking in the 93rd percentile statewide and earning five stars. It leads the local schools in ELA, math, and science, with an average proficiency of about 75%, and has improved substantially over the past three years. Sumner Middle School is the strongest secondary school academically, ranking in the 86th percentile and performing especially well in ELA. Its ranking has improved consistently, although math results should be monitored. Sumner High School ranks in the 78th percentile and has strong ELA, graduation, and dropout outcomes. However, its math and science proficiency are much lower than its literacy results.
Liberty Ridge Elementary has a notable science strength, but its ranking and scores declined sharply in all three subjects recently, making it the most important school to watch for improvement. Daffodil Valley Elementary has improved compared with three years ago and has respectable ELA performance, but its recent math and science declines—particularly in fifth grade—are concerns. For families comparing schools, Maple Lawn offers the strongest overall academic results, Sumner Middle shows encouraging momentum, and Sumner High combines strong graduation outcomes with a need for focused math and science support. Spending and student-teacher ratios differ among schools, but the data do not show a simple connection between those measures and test performance.
