Message From the School Director

atl text

At International School of Tanganyika, our mission is to challenge, support, and inspire our students to fulfil their potential and improve the world. Founded in 1963, IST has been working with expatriate and Tanzanian families for 60 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. Our greatest strength, however, is our commitment to the individuality of each child we serve. The recognition of each child’s unique self guides 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.

Go Twigas!

Melanie Vrba

IST Director

I enjoy being part of the whole community and I have been lucky that because of my children I could be a part of the school again. I always have positive things to say about the school and I felt thrilled that out of so many alumni, I was the one representing them all.

The best part about attending IST was the wealth knowledge I gained by being in such a culturally diverse environment. The standard of education was incredibly high, which inevitably meant that year one of university was a breeze.
Miranda Naiman, founder of Empower

The CAS program was/is very rich. I think that these service opportunities went a long way in shaping our sense of social justice and civic responsibility.

Everything is still so familiar and where I always felt safe as a child. And now I am making it a safe and fun place for all the kids. That’s quite amazing. Reminds me of my family a lot and how I grew up.
