Summary:

The 98198 ZIP code includes three high schools serving grades 9–12: Mount Rainier High School, Cascade Public Schools, and Maritime High School. The schools serve the local Highline-area community but differ greatly in size, structure, and reported outcomes. Mount Rainier is a large comprehensive school with 1,846 students, while Cascade and Maritime each enroll 126 students.

Mount Rainier High School has the strongest overall reported profile. Its 2024–25 graduation rate was 87.5%, above Washington’s 82.6%, and its dropout rate was 6.9%, below the state’s 9.8%. Its ranking also improved substantially, from the 32nd percentile in 2023–24 to the 51st percentile in 2025–26. Mount Rainier’s ELA proficiency was above the state average, but math and science were lower, making math the clearest academic improvement area. The school is part of the Highline School District.

Maritime High School, also in the Highline School District, is a small school with a strong ranking history, reaching the 55th percentile most recently and the 63rd percentile in 2023–24. Its 2024–25 ELA and math results were relatively favorable compared with the other schools, although math remained below the state average. Recent ELA and math results are suppressed, and graduation data are unavailable, so its current performance is difficult to assess fully. Cascade Public Schools, operated by Why Not You Academy, has low student-teacher ratios and higher spending per student but the weakest reported outcomes, including a 62% graduation rate and a ranking in the 4th percentile. Small-school results and suppressed figures should be interpreted cautiously.
