The school prepares students for the Tanzanian national examinations. There are four forms in the junior school, Forms I to IV; and two in the senior school Forms V and VI. Students usually arrive at the school around the age of thirteen or fourteen, having completed seven years at primary school. Some may have to delay their start at secondary school and may be as old as seventeen.
This is particularly true in Mvumi in which subsistence farming is the principal occupation. Rainfall is uncertain and there has been some serious drought over the past few years. It is a precarious existence.
Students take National Examinations in year II, IV and VI. The core subjects in Form I and II are: Civics, History, Geography, Kiswahili, Commerce, Book-keeping, Religious Studies, English, Biology, Chemistry, Physics, Mathematics and Computing. In Form III students choose either the Science stream or the Arts stream.
In calculating a student’s final grade in Form IV the student’s result in the Civics, Kiswahili, English and Mathematics are included, together with their three best subjects.
To proceed to the senior school a student needs to have earned at least three grade C’s in their Form IV examinations. Many Tanzanians fail to achieve this standard and the numbers progressing to Form V are reduced. DCT Mvumi offers a number of different subject combinations: History, Geography and English; Economics, Geography and Mathematics; Physics, Chemistry and Mathematics; Physics, Chemistry and Biology; Physics, Geography and Mathematics; History, Geography and English Language; Kiswahili, Geography and History.
Since its introduction in 2005 there has been a significant yearly growth in senior school numbers. In 2019 there were 130 students in the "A" Level Courses.
The school provides education for both boarding and day students. The demand is very high. Typically only about one half of those taking the entry examination will be able to be offered a place.
There is a great need for boarding for girls as they have an onerous job combining education with domestic work: women play a very active role in managing the ‘shamba’, or family plot.
The school provides a variety of activities: sports, debating, subject clubs, and choirs. It also has its own fibre link providing access to the internet. There are sporting fixtures, educational visits to places of interest, and engagment in debating and academic competitions.
