What Saint Mark's High School does
Saint Mark's High School is a private, nonprofit, college-preparatory coeducational Catholic high school located at 2501 Pike Creek Road in Wilmington, Delaware, founded in 1969 and operated under the Catholic Diocese of Wilmington. It is the only Diocesan high school in New Castle County, serving students drawn from Delaware, southeastern Pennsylvania, southern New Jersey, and Maryland, and admitting F-1 international students through the Diocese. For the 2026-2027 academic year, domestic tuition is $18,648 plus a $750 General Administrative Fee ($19,398 total), with international tuition at $22,378, and 65% of students receive financial aid. Reported outcomes include a 97% college-going rate at institutions such as UPenn, Villanova, Notre Dame, and the University of Delaware, 108 Delaware state athletic championships, and 60-65% enrollment growth over the past five years.
The school delivers its curriculum through standard college-prep academics with Advanced Placement courses, more than two dozen dual-enrollment options with local universities, 30+ academic electives, and the EMMAUS program for students with documented learning differences. Its technology infrastructure is conventional EdTech rather than proprietary: FACTS Family Portal and FACTS SIS for student information, RenWeb for admissions, MobileServe for service-hour tracking, MyKidsSpending for cafeteria payments, and eCatholic as the website CMS. Notable physical differentiators include the 3,200 sq ft S.T.R.I.P.E. Lab (Science, Technology, Robotics, Innovation, Prototyping, Engineering), an Esports Center, a Creative Media and Broadcast Center, a Low Ropes leadership course, an outdoor pavilion and classroom, and 84+ clubs, activities, and sports teams. Core technology is therefore a hybrid of off-the-shelf EdTech SaaS for administration and a portfolio of capital-intensive facilities that support STEM, arts, and athletics programming.
Revenue is generated from a tuition-and-fee base (subscription/recurring model), supplemented by annual giving (The Fund for Saint Mark's), the multi-year Building Champions capital campaign, the Spartan Business Alliance corporate sponsorship program (Platinum/Gold/Green tiers), a Spirit Shop, alumni commemorative bricks and Delaware license plates, a 1969 Legacy Society for planned giving, and Spartan Summer Camp programming. The go-to-market motion is admissions-led and direct: prospective families enter through the RenWeb application, the HSPT placement test, Spartan for a Day shadow visits, 7th Grade Spartan Morning Sessions, and campus tours, with applications accepted year-round and the Director and Associate Director of Admissions carrying named quotas. Institutional revenue is not publicly disclosed.
