Holy Rosary School (West Seattle)

Catholic parish school in the West Seattle Junction · grades PK-8 · 518 students (Washington State Board of Education, 2024-25) · Archdiocese of Seattle, accredited by the Western Catholic Educational Association (WCEA)

The verdict

Holy Rosary is the rare Puget Sound private school where the headline number is low, $11,314 for a single in-parish child in 2026-27 against $30,000-plus at secular independents, and the fine print is not about money but about membership. The discount is a covenant: six months of documented parish registration, Mass attendance "most Sundays," a ministry commitment, and a minimum $1,140 annual tithe, all verified before the subsidized rate applies. What that buys is one of the largest and most financially solid parochial elementaries in the region, with two classrooms per grade, K-2 reading specialists, tracked math from 5th grade, and a fundraising machine that cleared a million dollars last year. Practicing Catholic families in West Seattle should have it on the short list by default. Families who want secular pedagogy, published test outcomes, or a light parent-obligation load should read the requirements before falling for the price.
