Kilo Middle School, Auburn WA - Test Scores & Data

Original Research by School Decision on Kilo Middle School

Kilo Middle School serves grades six through eight in Auburn, Washington, as part of the Federal Way School District. It is a regular public school, neither a charter nor a magnet, and it sits within a mid-sized suburb in the Seattle metropolitan area. The school draws its students from a community that includes residential neighborhoods, a historic downtown core, and significant industrial employment centers, such as the large Boeing parts plant and Muckleshoot Tribal Enterprises.

The student body is diverse and economically mixed, though the share of students who qualify for free or reduced-price meals is substantial. The largest racial and ethnic groups are Hispanic students, followed by White, Asian, Black, Native Hawaiian or Pacific Islander, and students identifying with two or more races. A small number of American Indian or Alaska Native students are also enrolled. The school enrolls roughly an even number of students in each grade, with a total enrollment that is moderate for a middle school.

On state assessments given in the 2024-25 school year, proficiency rates in English language arts and math varied by grade. In math, proficiency was lowest among sixth graders and higher among seventh and eighth graders, all below half of students reaching the bar. In English language arts, proficiency rates were somewhat higher, with roughly two out of five students meeting standards in each grade. In eighth-grade science, about a third of students were proficient. When combined across all tested subjects and grades, the school's overall proficiency index places Kilo in the bottom quartile relative to other districts in King County, a comparison that groups it among the lower-performing schools in this region. Because this is the only year of testing data available, there is no trend to examine; performance may shift with future results.

Data on several other dimensions is absent. The school did not report its special education or English learner counts, and no information on discipline rates, chronic absenteeism, or staffing ratios was available. A parent may want to ask the school directly about these factors, as they can shape the day-to-day experience. Since Kilo is a middle school serving only grades six through eight, it has no graduation rate.

The community context in Auburn adds texture. The city has grown through annexations and large planned developments, including the Lakeland Hills community, which added its own elementary school and shopping center. The median household income sits near the national median, and the housing market in the area shows typical suburban patterns. Major employers include Boeing, the Auburn School District, MultiCare Auburn Medical Center, and Green River College, which together anchor a job base that mixes aerospace, health care, education, and retail. The Muckleshoot Indian Reservation lies to the south and southeast, and the city's downtown transit hub connects residents to the broader region.

For a family considering Kilo Middle School, the picture is straightforward. The school serves a diverse, lower-income student body in a suburban setting with deep industrial and civic roots. Academic proficiency on state tests is below average for the county, particularly in math. The lack of additional data on school climate, staffing, and course access means a parent will need to gather more details firsthand. This is a school where a family should visit, ask about supports for struggling students, and understand the academic programs available before making a decision. It fits a family that values a diverse community within a well-established suburb and is prepared to be actively involved in understanding and navigating the school’s academic pathway.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
