Tehran International School

"Tehran International School, known formally as Tehran International & Adaptive School (TIS), is an international school located in North Tehran, Iran, serving the educational needs of families seeking a globally recognized academic program in one of the region's most dynamic cities."

With English as the primary language of instruction and the prestigious International Baccalaureate Diploma Programme at the heart of its academic offering, TIS provides students with a rigorous, internationally oriented education designed to prepare them for university study and life beyond borders. Founded in 1994, the school has built its identity around the IB Diploma Programme, aligning itself with a globally respected curriculum framework that emphasizes critical thinking, intercultural understanding, and academic breadth. For expat families and relocating professionals, the presence of an IB DP school in Tehran offers meaningful continuity — students who have followed IB pathways elsewhere in the world will find a familiar and transferable academic structure at TIS, and those aiming for university admission internationally will benefit from the programme's worldwide recognition. The school operates across three campuses in the northern part of Tehran, reflecting both the practical realities of the local context and its commitment to serving a diverse student population. Boys attend classes at a campus in Saadat Abad, while girls are based in Shahrak-e Gharb, with a separate elementary campus for younger boys. Both neighborhoods sit in the northern reaches of Tehran, an area generally regarded as one of the more accessible and well-resourced parts of the city, offering families a relatively convenient base from which to engage with school life. As a public international school, TIS occupies a somewhat distinctive position — bringing the structure and academic ambition of an IB institution into a publicly supported framework. This combination speaks to a commitment to making internationally oriented education accessible within the Iranian context, and the school's longevity since 1994 reflects its ability to sustain that mission across decades of change. For families relocating to Tehran, TIS represents one of the few opportunities to enroll children in an English-medium, internationally accredited academic program within the city. The school's focus on the IB Diploma Programme makes it particularly well suited to older students in the secondary years who are preparing for competitive university applications, though families with younger children will want to explore the elementary provision and how it feeds into the upper school pathway. Choosing a school in an unfamiliar city is rarely straightforward, and families moving to Tehran will naturally have many questions about daily life, campus culture, and how the school community comes together. TIS, with its three-decade history and internationally recognized curriculum, offers a grounded starting point for those conversations. Prospective families are encouraged to reach out to the school directly to learn more about enrollment, campus visits, and how TIS might fit the specific needs of their children.
