The Report 191 business studies route, taken in trimesters at a TVET college.
NATED programmes, also called Report 191 courses, run in trimesters. Business Management runs from N4 through N6, with each level taking about six months of full time study.
After passing N6 you need to complete 18 months of relevant practical work experience before the National N Diploma is issued. Plan for that requirement early, because finding the placement is usually harder than passing the theory.
