Summary:
ZIP code 98359 is home to a single elementary school, Olalla Elementary School, located in Port Orchard, WA and serving grades PK–5 with 315 students as part of the South Kitsap School District. Because it is the only elementary school in the area, there are no local peers to compare it against; the most useful benchmarks are its own district and Washington state averages. Olalla holds a 4-star rating in each of the last three reported school years and ranked 173 out of 1,138 Washington schools in 2025–26, placing it in the 85th percentile — stronger than its district's 68th percentile and 3-star rating.
Math and science are Olalla's standout strengths. In 2025–26, all-grade math proficiency was 63.16%, well above the district's 43.59% and the state's 43.11%, while science reached 70.83% versus 52.85% district and 50.95% state — roughly 20-point advantages over state averages. Fifth-grade math was exceptional at 70.83%, compared with 46.91% in the district and 43.32% statewide. English language arts is more mixed: all-grade ELA was 54.89%, only slightly above the district's 54.65% and the state's 52.81%. Fourth-grade ELA was the one clear weak spot at 44.68%, below both the district's 50.07% and the state's 50.43%. Science held essentially flat year over year (70.73% to 70.83%), while all-grade ELA fell 6.14 points and math slipped 3.26 points; these changes involve different student cohorts rather than the same students tracked over time.
With 39.68% of students qualifying for free or reduced lunch, per-student spending of $21,137 (2023–24), and a student-teacher ratio of 13.7, Olalla serves a population with meaningful economic need while producing well-above-average results in math and science. For families in this ZIP code, the takeaway is a single, high-performing neighborhood school with strong math and science outcomes, a solid overall state ranking, and ELA — particularly in 4th grade — as the area to watch.
