Research dossier

St. John Catholic School

Catholic parish school in Seattle's Greenwood neighborhood · preschool plus K-8 · 475 K-8 students plus 57 preschoolers (Washington State Board of Education, 2024-25) · run by St. John the Evangelist Parish under the Archdiocese of Seattle

The verdict

Most private-school comparisons start with a price. St. John doesn't really have one. It has a pledge. Under the parish's "Fair Share" stewardship model, the 2026-27 cost to educate is $14,875 per K-8 student. Out-of-parish families pay that full amount, while active parishioners pledge what they can honestly afford against suggested rates of $11,156 for a first child, sliding to $7,229 for a third. The catch is that "active parishioner" is a monitored status, meaning registered giving, regular Mass attendance, ministry participation, and a mandatory November parish meeting. On top of that, the school requires 40 volunteer hours a year from two-parent households plus attendance at a late-January State of the School presentation just to keep re-enrollment priority. The buy-in purchases one of North Seattle's largest and most stable parish schools: two-section grades of roughly 50 kids, a sports program pulling in over 80% of students, and a pipeline aimed at Seattle Prep, Blanchet, Holy Names, and O'Dea. Families who want a school they can simply pay for and drop off at should read the fine print twice. Families ready to join a parish, not just a school, will find the economics and community unusually strong.
