In our school, we are committed to offer first class education to all students, which will enable them to be responsible citizens of the world, future leaders, and reach their goals in life. To meet the needs of the community we offer two curricula, Tanzania national curriculum (NECTA) and International curriculum (Middle School Programme, IGCSE and IBDP). NECTA curriculum runs from Form 1 to 6. International curriculum covers Middle School Programme; this is offered from year 7 to 9 leading to International General Certificate for Secondary Education (IGCSE) which is year 10 to 11. International Baccalaureate Diploma (IBDP) is a two year pre-university course offered in year 12 and 13. Our International curriculum is based on IB philosophy of preparing well rounded learners in both academics and spiritual wisdom. To meet this goal, our focus is not only on academic achievements of the students, but we also encourage their participation in sports, community service, creativity and action across the entire school. Mzizima has, since the 1980s, been at the forefront of educational innovation in Dar-es-Salaam and was one of the first schools to introduce inquiry-based learning methodologies and to integrate IT into all aspects of school life.

The School is divided into Lower School and Upper School. Lower School is Years 7- 9 and Forms 1 and 2. Upper School is Years 10 - 13 and Forms 3 - 6. The normal ages for entry are given in the table below.
