International School of Tanganyika

The International School of Tanganyika (IST) is the most prestigious and longest-established international school in Tanzania, widely regarded as the leading institution for internationally mobile families in Dar es Salaam. IST serves students from Pre-Kindergarten through Grade 12, offering the International Baccalaureate (IB) Diploma Programme to senior students alongside an American-aligned curriculum across all year groups. The school is fully accredited by both the Council of International Schools (CIS) and the Middle States Association (MSA-CESS), the world's two most respected international school accrediting bodies — ensuring globally consistent educational standards. IST's Upanga campus on United Nations Road is ideally situated in Dar es Salaam's diplomatic district, making it the natural choice for UN staff, diplomatic families, and international business executives in Tanzania's commercial capital. The school serves a highly diverse student body representing dozens of nationalities. Facilities are exceptional, featuring modern science laboratories, performing arts spaces, a library, and comprehensive sports facilities. IST's long legacy of academic excellence, internationally experienced teaching staff, and dual IB/American qualification pathway make it the flagship international school in East Africa's Indian Ocean coastline.
