Enrollment by grade, 2024-25 school year, as reported to the WA State Board of Education.
NCES Private School Universe Survey, 2021-22 (the most recent federal collection). Private-school demographics are reported biennially and lag public-school data.
Catholic parish school on Capitol Hill, Seattle · K-8, plus an infant-through-Pre-K Early Learning Center · 578 K-8 students (Washington State Board of Education, 2024-25) · the only Jesuit parish grade school in Seattle, under the Archdiocese of Seattle.
St. Joseph is a parish school wearing an independent school's clothes. At 578 students it is among the largest Catholic grade schools in the region, big enough to fund what small parochials cannot: a Learning Resource Center, trimester electives from Rock Band to Music Production, and a new Early Learning Center campus in Roanoke Park. The price matches the posture. Tuition runs $20,276 for K-4 and $21,264 for grades 5-8 in 2026-27, with no published parishioner discount, an October-to-February application season, and an auction-and-annual-fund culture straight from the independent-school playbook. The fact most families miss sits in the enrollment table: cohorts jump from 50 second graders to 70 third graders, and from 57 fifth graders to 75 sixth graders. Grade 3 and grade 6 are real side doors for public-school families, not just kindergarten. The payoff most families are buying is the pipeline into Seattle's selective Catholic high schools, and Seattle Prep sits a mile north sharing the school's Jesuit vocabulary. Look elsewhere if you want religion optional (it isn't) or a transactional drop-off school. This community expects your evenings, your volunteer energy, and your paddle at the auction.
