Colegio de Todos Los Santos

"Colegio de Todos Los Santos is a private international school located in Villa Adelina, Argentina, offering families a well-established bilingual education grounded in the globally recognized International Baccalaureate framework."

With a history stretching back to its founding in 1981, the school has built a lasting presence in the Buenos Aires metropolitan area, earning its status as an IB World School in 1988 — a designation that reflects a sustained commitment to rigorous, internationally minded education. The school's academic program centers on the IB Diploma Programme, the prestigious two-year curriculum designed for students in the final years of secondary school. The Diploma Programme is widely respected by universities around the world and challenges students to think critically, engage with diverse perspectives, and develop the research and writing skills that higher education demands. For families relocating internationally, the IB credential offers an important continuity of academic standards, making it easier for students to transition into or out of the program regardless of where their educational journey has taken them. One of the school's defining characteristics is its bilingual approach to instruction, with classes delivered in both English and Spanish. This dual-language model reflects the school's identity as a bridge between Argentine culture and the broader international community. Students who come to Colegio de Todos Los Santos gain meaningful fluency and academic literacy in both languages — an asset that serves them well whether they continue their studies in Argentina, return to an English-speaking country, or pursue opportunities anywhere else in the world. For expat families in particular, the English-language instruction provides important reassurance, while the Spanish immersion supports genuine integration into Argentine life. Villa Adelina is a residential neighborhood in the northern zone of greater Buenos Aires, in the Partido de San Isidro. The area is home to a number of international and private schools and is a familiar destination for expat families and professionals who settle in the northern suburbs of the Argentine capital. The surrounding community tends to be family-oriented and relatively accessible from the city center, making it a practical choice for those navigating the logistics of relocation. What sets Colegio de Todos Los Santos apart is the combination of longevity and international accreditation. Having operated continuously since the early 1980s and having held IB World School status for well over three decades, the school brings a depth of institutional experience that newer programs simply cannot match. Families evaluating schools for academically motivated students — especially those with an eye toward international university placement — will find in Colegio de Todos Los Santos a school that takes both intellectual development and global citizenship seriously. The bilingual environment, the IB Diploma Programme, and the school's deep roots in the Villa Adelina community together make it a compelling option for expat families and relocating professionals seeking quality, continuity, and a genuinely international education in Argentina.
