For many years UNISA continued as a testing center where students working on credits at universities like Oxford and Cambridge could take exams and check their credits (UNISA , The history 2013). UNISA changed direction in 1946 when Professor van der Walt was tasked with determining whether correspondence education was a viable option for the institution (UNISA, The history 2013).
