Original Research by School Decision on Decatur High School
Decatur High School sits in Federal Way, a mid-sized city in King County that grew from a logging settlement into a bedroom community for Seattle and Tacoma after the interstate arrived. The city is primarily car-oriented, with landscaped apartment complexes, strip malls, and big-box retail along major roads, but a new Link light rail station opened at the Federal Way Downtown station in late 2025, which may shift how people move around the City Center area. The school itself is a regular public high school serving grades nine through twelve, part of the Federal Way School District.
The student body is diverse. The largest groups are students who identify as Hispanic, followed by white students, then those who identify as two or more races, Black students, Asian students, Native Hawaiian or Pacific Islander students, and a small number of American Indian or Alaska Native students. A substantial share of students come from low-income households, as measured by eligibility for free or reduced-price lunch. The school has a large enrollment for a high school, with a fairly even distribution across all four grade levels.
On state assessments, Decatur’s results show a mixed picture. In English language arts, roughly half of students met the proficiency standard. In science, about a quarter did. In math, the share of students reaching proficiency was markedly lower. These results represent a single year of data, so there is no trend to examine. A parent may want to look into this further with the school to understand how the school supports students who are not yet at the proficiency benchmark, especially in math.
The school offered no data on chronic absenteeism, discipline, course access, or staffing. We also looked for information on special populations such as students with disabilities and English learners, but the data was not available. These gaps mean a full picture of school climate and support systems is not possible from this source alone. The district's parent-relevant changes were also limited; publicly reported information did not turn up much of lasting impact.
Housing in the area reflects a high-cost market, with home values around the zip code somewhat higher than the national median but below the King County median. Rents are elevated as well. The city saw a modest population decline between the 2020 census and a 2024 estimate, and voters rejected a proposed annexation of East Federal Way in the past. The most significant recent development is the light rail extension, which opened in late 2025 and may affect commuting patterns and long-term growth.
Federal Way has a range of civic anchors and employers. The school district itself is among the largest employers. World Vision International, a regional hospital, and the U.S. Postal Service also employ many people. The former Weyerhaeuser headquarters campus has been redeveloped into a corporate park with office, industrial, and lab space. Parks and trails are abundant, including a three-mile paved trail and a lakefront state park. The Performing Arts & Event Center and Town Square Park anchor the civic core.
Decatur High School serves a large, diverse student population in a city that is suburban in feel but gaining transit connections. Academic proficiency, particularly in math, is an area where families will want to seek more detail. The lack of data on discipline, attendance, and special programs limits what can be said about the day-to-day environment. For a family considering this school, visiting and asking about academic support structures and school culture would be a natural next step.
