Celtic International School de Mexico

"Celtic International School de Mexico, located in Mexico City, is a private international school offering a rigorous, globally minded education to students from pre-kindergarten through grade 12."

Founded in 2006, the school has built its reputation on the internationally recognized framework of the International Baccalaureate, providing families with a curriculum trusted by educators and universities around the world. At the heart of Celtic International School's academic program is a commitment to the full continuum of IB education. The school offers the Primary Years Programme for its youngest learners, nurturing curiosity and foundational skills through an inquiry-based approach. As students progress, they enter the Middle Years Programme, which deepens critical thinking and interdisciplinary understanding across a broad range of subjects. At the upper secondary level, the school delivers the Career-related Programme, which combines the intellectual rigor of the IB with practical, career-oriented learning — an increasingly valued pathway for students who wish to connect their academic work with real-world professional contexts. Together, these three programmes create a coherent, developmental journey from the earliest years of schooling through to graduation. One of the school's defining characteristics is its bilingual environment. Instruction is delivered in both English and Spanish, reflecting the school's dual identity as an institution rooted in Mexican culture while also preparing students for an interconnected global world. This bilingual foundation is particularly well suited to the diverse families the school serves, including Mexican nationals seeking an internationally accredited education and expatriate or relocating families who need their children to thrive academically in English while also gaining genuine fluency and cultural literacy in Spanish. Celtic International School de Mexico sits within Mexico City, one of Latin America's most dynamic and culturally rich metropolitan centers. Families considering a relocation to the city will find the school's international orientation a natural fit for the cosmopolitan environment Mexico City offers, with its world-class arts, cuisine, history, and growing professional communities across industries. The school's association with the Cumbres educational network — reflected in its web presence at cumbresmexico. com — situates it within a broader institutional framework with established experience in Mexican private education, lending additional stability and resources to its international program. This connection suggests a school that benefits from both the global standards of the IB and the grounded expertise of an experienced local educational organization. For expat families and relocating professionals evaluating options in Mexico City, Celtic International School de Mexico presents a compelling combination: an internationally portable IB curriculum delivered across all school years, a genuinely bilingual learning environment, and a school community that has been developing its programs since 2006. Families who prioritize academic rigor, language development in both English and Spanish, and a clear through-line from early childhood to secondary graduation will find this school worthy of serious consideration as they plan their next chapter in one of the world's great cities.
