Seattle Christian Schools is a private K-12 evangelical interdenominational Christian school on a 13-acre Military Road campus in SeaTac, founded in 1946 as the first evangelical interdenominational Christian school in Western Washington. The school enrolls roughly 510 students with a 12:1 student-teacher ratio and tuition near $14,350, and was dually re-accredited by ACSI and Cognia for a six-year period in 2025.
Among Western Washington's larger evangelical K-12 schools — Cedar Park Christian (Bothell, ~1,000 students), Lynden Christian (~1,200), and Cascade Christian (Puyallup, ~1,900) — Seattle Christian sits at the smaller, somewhat stronger-academic end. The average GPA runs around 3.59, the four-year graduation rate is 100%, and the average SAT mean is around 1190. AP coursework is offered alongside the faith-based core curriculum, and the school appears in PolarisList's Washington Harvard / Princeton / MIT placement rankings.
The school operates without affiliation to any single denomination and draws families from across the south King County corridor — Burien, Federal Way, Des Moines, Tukwila, and SeaTac. It moved to its current Military Road campus in 1997 after an earlier expansion, and the consistent 100% graduation rate combined with the still-modest SAT mean makes it a defensibly mid-tier fit for evangelical families prioritizing faith integration over selective-college placement.
