Summary

Sumner Middle School serves approximately 674 students in grades 6–8 in Sumner, Washington, a community within the highly rated Sumner-Bonney Lake School District.

For parents, the school’s overall profile is strong: it ranks 72nd out of 514 Washington middle schools, placing it in the 86th percentile and earning a four-star rating. Students perform well above state averages in every tested subject. English Language Arts is the clearest strength, with 70.34% of students meeting standards and fairly consistent results across grades. Math proficiency is 55.05%, but 7th grade is notably weaker than 6th and 8th grades. Science, at 56.05%, is also above the state average but is the school’s largest local gap. By comparison, Lakeridge Middle School currently outperforms Sumner in all three subjects, while Mountain View Middle School has a substantially stronger science result. North Tapps Middle School has similar ELA and math results but much higher science performance.

Sumner has improved considerably over time, moving from the 68th percentile in 2020–2021 to the 86th percentile today. ELA has risen steadily, and science has recovered from a low point in 2023–2024, although science and 7th-grade math remain important growth areas. The school’s effectiveness ranking for low-income students is especially strong, at the 91st percentile statewide. Special education and English Language Learner effectiveness rankings are more moderate and have declined in recent years, making them areas worth monitoring. Staffing is favorable compared with nearby schools: the student-teacher ratio is 19.0, lower than at Mountain View and Lakeridge. Overall, Sumner is a high-performing, improving school, though several nearby schools currently post stronger results in specific subjects.
