The Charter School of Wilmington

What The Charter School of Wilmington does

The Charter School of Wilmington is a public charter high school founded in 1996 and located at 100 N. DuPont Road, Wilmington, Delaware. It serves grades 9 through 12 with a curriculum concentrated on science, mathematics, and technology, complemented by 25 AP course offerings, a STEM Research Project and Science Fair program, and academic departments spanning mathematics, science, English, social science, world language, computer science, PE/health, and student support services. The school markets itself as the #1 rated high school in Delaware, citing a 100% graduation rate, 99% college matriculation rate, average SAT score of 1258, 25 varsity sports teams, and more than 100 student-run clubs, with 65% of faculty holding advanced degrees.

The institution operates as a Delaware nonprofit under state charter school law and is governed by its own Board of Directors with no parent company or private equity ownership. Revenue is generated through per-pupil state allocations supplemented by voluntary donations routed through a Donate Online portal, the CSW Endowment Fund, and a Charter School Funding program. Student recruitment runs through structured Ninth Grade Admissions and Transfer Admissions pathways, supported by a community-led go-to-market motion spanning the PTSO, alumni networks, an events calendar, and organic social channels on Facebook and Instagram. Distribution and stakeholder communications rely on a modest technology stack — Apptegy CMS for the website, Thrillshare for document management, Heyzine for the digital course book, Velocity Payment for online payments, and iOS/Android mobile applications.

The leadership team comprises a Head of School (Dan Bartnik), Principal (Dr. Maura Kelly Triebenbacher), Assistant Principal (Kyle Berger), CFO (Tonya Dempsey), and functional directors covering development, athletics/facilities, technology, communications, admissions, and HR. There are no disclosed funding rounds, acquisitions, subsidiaries, patents, trademarks, or AI/ML capabilities, and no revenue figures are publicly available.
