International School of Athens

"The International School of Athens (ISA) is an independent, English-medium school situated in Kifissia, a leafy and well-regarded residential suburb to the north of Athens."

Serving students from pre-kindergarten through Grade 12, ISA offers families a cohesive, internationally recognized education within one of Europe's most historically rich cities. Founded in 1972, ISA has built a long-standing presence in the Athens expatriate and international community. Formerly known as TASIS, the school has evolved over the decades into a fully authorized International Baccalaureate institution, offering all three core IB programmes: the Primary Years Programme (PYP) for younger students, the Middle Years Programme (MYP) for the middle school years, and the Diploma Programme (DP) at the senior secondary level. This unbroken IB continuum means that students can progress from their earliest years of schooling through to university preparation within a single, philosophically consistent framework — one that emphasizes inquiry-based learning, international-mindedness, and the development of the whole child. English is the primary language of instruction throughout the school, making ISA a natural fit for expat families arriving from English-speaking countries as well as for internationally mobile families for whom English is the common academic language. This focus on English-medium education, combined with the globally portable IB qualification, ensures that students are well-positioned whether they move on to universities in Europe, North America, or elsewhere in the world. The school's Kifissia setting is a distinct advantage for families considering life in Athens. Known for its tree-lined streets, cooler climate, and quieter pace relative to the city centre, Kifissia is one of the most sought-after areas for international residents and professionals relocating to Greece. The neighborhood provides a comfortable and accessible base, with good transport links to central Athens while retaining a suburban character that many families find appealing. ISA draws its student body primarily from the international community in Athens, including the families of diplomats, multinational company employees, and professionals assigned to Greece on a temporary or longer-term basis. This diverse mix of nationalities creates a genuinely international school culture, where students are accustomed to engaging with peers from a wide range of backgrounds and perspectives — an environment that complements the values at the heart of the IB philosophy. What distinguishes ISA is the combination of its longevity, its complete IB pathway from early childhood through to the Diploma, and its location within one of the world's great capital cities. Students benefit not only from a rigorous academic programme but also from the extraordinary cultural, historical, and geographical context that Athens provides. For families navigating a relocation to Greece, ISA represents a stable, established, and internationally oriented choice — a school where children can settle, thrive academically, and grow into globally aware young people.
