Marist Brothers Secondary School Dete was opened in 1972, as a transfer from St. Mary’s Secondary School in Lukosi,
Hwange. St Mary’s Secondary School had been an old Catholic School run by the priests of the Hwange Diocese. Marist in Dete has classes from Form 1 to Form 4. Academic subjects studied include English Language, English Literature, Ndebele, Mathematics, Geography, Science, Biology, and Bible Knowledge. The school also offers practical subjects including Metalwork, Bicycle Mechanics, Motor Mechanics, Woodwork (Carpentry), Needlework, and Cookery (Food and Nutrition). Typically, every student will produce and take home several pieces of furniture or clothing that they will have produced during the year, for their personal or family use. Marist motor mechanics students and their teachers have, over the years, created usable motor vehicles using scrap. The most notable of these were
Moonshine, a large truck that was used to ferry goods from Dete to and around the school, and
Sunshine, a small 'body' on 'wheels' runaround vehicle used around the school and farm area. Typically, these vehicles were deliberately never developed to the point of being roadworthy, and were made to lack things such as wind screens, batteries. In 2014 MBSS came in 17th in the country with 87.3% of its students passing. Students from the school have been among those having the highest scores in the ZIMEC A-level exam. In 2016, the school's quiz team won first place in a contest held in
Johannesburg, with 23 schools from South Africa, Botswana, Zambia and Zimbabwe participating. ==School life==
