What Windsor School does

The Windsor School is an independent, coeducational private college preparatory school serving students in Grades 7-12, located at a single campus at 37-02 Main Street in Flushing, Queens, New York. The school operates three core service lines: the regular middle and high school academic program aligned to New York State Regents standards; an accredited six-week Summer School Program (in its 46th year by 2026) offering Regents-level courses for credit advancement, enrichment, and preview; and an intensive English Language Learner (ELL) program with class sizes of 5-7 students for international enrollees. Supporting services include a Homestay Program for international student housing and a Merit Scholarship Program awarding 25%-75% of tuition to qualifying students.

The school's revenue model is primarily tuition-based (subscription/recurring), with secondary income from summer school fees ($880 per class; $1,760 for full-year credit; $680-$800 science lab fees) and international student services including ESL instruction, TOEFL preparation, and I-20 visa document issuance. Pricing is not publicly disclosed for annual tuition. The institution holds four regulatory credentials that together form a meaningful barrier to entry: NY State Education Department registration, Middle States Association 7-year reaccreditation (through May 2018), College Board/CSS membership, and SEVP federal authorization to enroll F-1 non-immigrant students. International students — historically drawn from a formalized partnership with Guangxi Normal University in China — represent a long-standing second customer segment alongside local NY-area families.

The institution is privately held with no disclosed parent company, external investment, or M&A activity. Leadership consists of Principal James DeFeo (promoted internally from Social Studies teacher) and Assistant Principal / School Counselor / College Advisor Catlyn Triolo. Headcount is reported at 114 employees. The Math League team has placed first statewide with a perfect score (2012) and maintained top-two statewide rankings across most years from 2010 through 2025, providing a measurable academic-reputation signal. No digital products, apps, APIs, or AI capabilities are documented.
