ZIP code 98134 has one public school, Summit Public School: Sierra, a small high school serving grades 9–12 in Seattle. The school enrolls 214 students and has a student-teacher ratio of 15.2 to 1, so year-to-year results may change noticeably when outcomes involve relatively small groups of students. Because it is the only public school in the ZIP code, there are no local school-to-school comparisons.

English Language Arts is the clearest strength: 62.5% of students were proficient in 2025–2026, about 10 percentage points above the Washington average, and performance improved by nearly 11 points from the previous year. Math is the largest concern, with 26.47% proficiency compared with 43.11% statewide.
