Summary:
ZIP code 98346 is home to a single middle school: Kingston Middle School, a grades 6–8 school with 455 students in the North Kitsap School District on Washington's Kitsap Peninsula. Nearly half its students (48.79%) qualify for free or reduced-price lunch, spending runs $19,424 per student, and the student–teacher ratio is 19.4. Because there is only one middle school in the ZIP, there is no local peer to compare against — the useful benchmarks are the district, which is strong (ranked 47th of 238 districts, 80th percentile, 4 stars), and the state.
Academically, Kingston's clearest strength is seventh-grade math: 45.59% of seventh graders met the standard, about 4.3 points above the state and the only subject-grade result where the school beats Washington overall. Schoolwide math (40.41%) lands within 2.70 points of the state, while ELA (45.5%) trails by 7.31 points — an unusual pattern, since reading normally outpaces math. Every subject improved year over year: ELA +3.59 points, math +5.94, and science +8.45. That improvement matches the school's rating recovery, from the 38th percentile (2 stars) in 2024–25 to the 55th percentile (3 stars) in 2025–26, slightly above its 2023–24 mark.
Two things for parents to watch. Sixth grade is the pressure point: just 40% proficient in ELA and 36.71% in math, both below state averages, with performance rising in seventh grade. And the school trails its district in all ten reported comparisons, most sharply in science, where the district's program is exceptionally strong. With two years of test data and one year each for poverty, spending, and staffing, trends in those areas cannot yet be judged — and there are no subgroup breakdowns to show which students need the most support.
