Renton Prep Christian School (Amazing Grace Renton Prep) is a PreK-10 Lutheran Church-Missouri Synod school in Renton, formed when Amazing Grace Christian School merged with Renton Prep at 200 Mill Plaza after a five-year planning process. Enrollment is approximately 220-240 students. The school's distinguishing claim is being Washington's first Cognia STEM-certified K-12 and a designated Microsoft Showcase School — the technology-integration positioning is unusual for an LCMS Christian school.
Within South King County's Christian-school market, Renton Prep's peer set is Forest Ridge of the Sacred Heart (Bellevue, Catholic girls 5-12), Bellevue Christian (Clyde Hill, K-12), Eastside Christian School (Bellevue, K-8), and the regional LCMS network (Trinity Lutheran in Bothell, Zion in Lake Stevens). For high-school continuation, Renton families weigh Renton Prep's accelerated 9-10 program against Cedar Park Christian's full 9-12, Bellevue Christian, or public Renton-area high schools. The Genesis Project — a service-learning initiative — is a visible part of the school's identity.
The primary school runs PreK-5, middle school 6-8, and a two-year accelerated 9-10 high-school program rather than full 9-12, which is a real structural commitment for families weighing transition logistics. Tuition runs around $16,750. The student-teacher ratio is approximately 13:1.
