Why choose St. Constantine’s International School ?

We are a high-achieving, happy, British education based school, with a Tanzanian heart. This is where future leaders are created. Our happy school is built on the notion that pupils develop a strong self-concept, because they are challenged appropriately every day through the highest quality teaching and learning. This means pupils learn to stand on their own two feet, to be resilient, so they persist in the face of difficulty. In so doing, they become independent learners who are prepared for twenty-first century life and leadership in a global world.
