Three Rivers Christian School is a nondenominational evangelical PK-12 in Longview, Washington, serving roughly 540 students across the Cowlitz County region. It is affiliated with the Association of Christian Schools International (ACSI) and is the dominant private school in southwest Washington's Three Rivers area (Longview, Kelso, and surrounding communities).
TRCS's peer set is regional rather than statewide. The closest comparisons are other ACSI-affiliated evangelical K-12s in southwest Washington and northwest Oregon — Cascade Christian (Puyallup), the Vancouver-area King's Way Christian and Vancouver Christian, and the smaller Bible-belt Christian schools scattered across Cowlitz, Lewis, and Clark counties. Compared to the major Seattle / Bellevue Christian K-12s (Cedar Park, Lynden Christian), TRCS is smaller and operates at a lower price point, reflecting both Cowlitz County demographics and a regional rather than metro-area draw.
The core tradeoff for Longview-area families weighing TRCS is the standard one in evangelical-Christian K-12 markets: continuous K-12 faith-integrated curriculum and a family community spanning all 13 grade levels, against larger and more academically differentiated public high schools (Mark Morris, R.A. Long, Kelso) where AP and advanced-track options are deeper. Tuition is approximately $6,450 at the highest grade — well below Seattle Christian-school norms and consistent with the regional market.
