St. Mary's International College

What St. Mary's International College does

St. Mary's International College (legal name: Colegio Internacional Santa María del Buen Ayre) is a private bilingual K-12 institution located on a three-hectare campus in Ezeiza, Buenos Aires Province, Argentina. Founded in 1958 by Susana Raquel Raffo, the school delivers Spanish-English bilingual instruction from Early Childhood (Nivel Inicial) through Secondary (Nivel Secundario), with French offered as a third language. It is recognized by the Dirección General de Cultura y Educación de la Provincia de Buenos Aires, enabling it to grant national academic titles, and holds accreditations from the International Baccalaureate Organization (IBO) and University of Cambridge International Education, permitting it to award the IB Diploma (mandatory for Quinto and Sexto Año), IGCSE, and ICE certifications.

The institution's core product is the bilingual curriculum, layered with international certification pathways and supplementary modules in technology and computer science (robotics, Scratch/LightBot, 3D printing, and UTN/Cambridge ICT certifications), music and theater (including a secondary-level Orquesta Sinfónica Académica), visual arts, sports (hockey, football, rugby, volleyball, athletics), community service culminating in the IB CAS component, and a School Houses engagement system (ASH/FIR/OAK). On-campus support services include a dining program operated by concessionaire Dafood, a bookstore with photocopying, and a uniform shop. English language certifications span Pre A1 Starters through CPE, and French DELF A1/A2 certifications are offered through Alliance Française.

The business model is direct-to-family enrollment: prospective families submit inquiries through the school's website (stmarys.edu.ar), complete an interview and campus tour, and submit documentation including identity records, vaccination certificates, and prior academic records. Pricing is not publicly disclosed. There is no evidence of external investment, parent company ownership, or private equity involvement; the institution operates under a Board of Directors (Consejo Directivo) with the founder serving as Directora General. The institution does not maintain its own mobile application, and its digital presence is limited to the website and a Facebook page.
