South Africa has experienced radical political and social change since 1994. Recognised for their role in the transformation process, universities have been and remain at the forefront of this change. While learners recognise that higher education is paramount to changing their socioeconomic condition, the massification of education along with new and advanced curricula has presented ongoing challenges for both universities and learners. Coming from diverse backgrounds and dealing with a variety of academic choices, learners encounter many challenges to entering Higher Education (HE). University programmes accept learners with varying competency levels and needs but are required to ensure that graduates meet standards that are acceptable to both industry and the academia. In the quest for universities to improve the delivery of educationally sound and industrially relevant programmes, ongoing research is being conducted and new and innovative ways have had to be developed to solve the problems associated with larger numbers of underprepared learners. An emerging method being employed in HE is the use of Data Analytics and Education Data Mining (EDM) techniques to derive solutions to assist institutions in maximising retention, and through-put rates. Durban University of Technology (DUT) has, since 1994, accepted learners into the Report 151 National Diploma from Technical Vocational Education and Training (TVET) Colleges. These learners, in respect to the Articulation Policy for the Post-School Education and Training (PSET) system of South Africa in terms of Section 8(2)(b) of the NQF Act, 2008 (Act 67 of 2008), are among those referred to as articulating learners. The perception among DUT staff involved with the teaching of these learners, is that they are as able to cope with the complexity and quality of engineering programmes as those learners entering the institution directly after completing their school leaving Senior Certificate/National Senior Certificate (SC/NSC). As no previous formal tracking, analysis or research has been conducted to determine the success or failure of learners articulating from TVET Colleges into DUT in general or into DUT’s Department of Electrical Power Engineering specifically, this research utilised Educational Data Mining and Inferential Statistics on an engineering learner dataset, to determine hidden patterns and relationships. Specifically, those relationships that promote progression, correlation, and selection were investigated. The Waikato Environment for Knowledge Analysis (WEKA) was employed to do the EDM, and a tool was developed to assist with the selection of learners entering the department, as well as ranking those entrance requirements that affect course content and throughput and various statistical methods were employed to conduct a retrospective longitudinal study. The Knowledge Discovery in Databases Process is used to work with 5 years of learner data. Both from the perspective of the progression of learners from semester 1 to semester 2 and the cohort throughput analysis, the results showed that there were no statistically significant differences in the performance of learners articulating from TVET colleges into the National Diploma: Electrical Engineering at DUT and their counterparts from high school admitted directly in the said qualification. The findings are that learners from a TVET College articulating into an HEI qualification, specifically the National Diploma: Electrical Engineering at DUT, complete the course in similar rates and in similar proportions to those learners admitted directly from school. The statistical analysis indicates that 77.6% of TVET N4 learners are promoted to semester 2, compared to 70.0% of SC/NSC learners and the EDM prediction tool developed for TVET N4 learners, the IBK classification tool resulted in a 77.61% accuracy, while the ANN classification tool returned an accuracy of 77.56% for the SC/NSC learners.
