She obtained a BA degree through UNISA, majoring in Archaeology and Anthropology, and an Honours degree in Archaeology (cum laude) at the University of Pretoria and a Masters degree in Historical Archaeology through UNISA in 2012 with thesis title: ‘n Histories-Argeologiese studie van die plaas Welkomskraal, distrik Venterstad, Noordoos-Kaap.
