Summary:
ZIP code 98118 has three high schools serving grades 9–12: Rainier Beach High School, Interagency Open Doors, and Alan T. Sugiyama High School. All are part of Seattle School District No. 1, which ranks in the upper third of Washington districts. Together, they enroll 1,034 students, but they serve different school models and vary greatly in size, so parents should be cautious when comparing their percentages directly.
Rainier Beach High School is the largest and most comprehensive option, with 854 students and the most complete current performance data. Its 83.7% graduation rate is slightly above the state rate, while its 7.6% dropout rate is below both the district and state rates. Test scores remain below district and state averages, particularly in science, but the school showed meaningful improvement in 2025–26: math proficiency rose to 34.43% and science proficiency to 32.08%. Its ranking also improved from the 8th to the 34th percentile over two years. This combination of improving academic results and comparatively solid graduation outcomes makes Rainier Beach the clearest choice for families seeking a traditional high school with available performance evidence.
Alan T. Sugiyama High School is much smaller, with 48 students, a low 8.8:1 student-teacher ratio, and unusually high reported spending per student. Its 71.0% graduation rate is below both district and state rates, while current test results are suppressed. Interagency Open Doors enrolls 132 students but has no reported graduation, dropout, testing, or ranking results in this dataset. It should be evaluated using program-appropriate measures rather than missing data. Overall, Rainier Beach offers the strongest evidence of current performance, while the two smaller schools require more individualized information about their programs and student outcomes.
