Zip code 98391 includes eight schools serving elementary, middle, and high school students, with five elementary schools, two middle schools, and one high school enrolling 5,618 students across the Sumner-Bonney Lake and Dieringer districts. The area’s schools generally perform well compared with Washington averages, and both districts rank among the state’s strongest: Sumner-Bonney Lake School District ranks 13th of 238, while Dieringer School District ranks ninth.
Tehaleh Heights Elementary School is the clearest academic standout, ranking 39th among Washington elementary schools and posting 85% proficiency in both English language arts and math. Victor Falls Elementary has shown the strongest recent improvement, rising from rank 276 to 97 over three years, while also achieving about 75% proficiency in ELA and math. Other elementary options include Donald Eismann Elementary, Dieringer Heights Elementary, and Lake Tapps Elementary, which serves grades 1–3. Lake Tapps has the lowest student-teacher ratio and highest reported spending, but its ELA results trail the district even though they remain above the state.
Among middle schools, Lakeridge Middle School ranks highest and is particularly strong in science, while North Tapps Middle School has maintained a consistently strong ranking. Bonney Lake High School stands out for a 94.1% graduation rate and a very low 2.1% dropout rate.

Overall, elementary schools lead the area in math, science has improved at most schools, and secondary mathematics is the main issue for parents to monitor.
