Welcome to IST



Our mission is to challenge, support and inspire our students to fulfil their potential and improve the world. Founded in 1963, we have been working with expatriate and Tanzanian families for over 50 years. Our longevity and strong international reputation has been developed through effective partnerships with our local community, strong academic results, and a well-balanced curriculum which allows students to explore their passions and interests.

IST has many strengths as a school community; a rigorous academic curriculum, experienced and devoted faculty members, strong parent support networks, excellent facilities and a belief in a balanced educational program. That being said, our greatest strength is our commitment to the unique nature of each child we serve. This belief pervades all that we do, and is central to our ability to reach our mission.

We are extremely proud of our school and the opportunities that exist for all students within the IST community. I invite you to explore our website to learn more about our school’s mission, vision, values and programs. If you have any questions about IST, please do not hesitate to contact us at your convenience.
