The study was undertaken to investigate the effectiveness of the interventions made by the Mogale City Plato mentorship programme to promote growth and sustainability of SMMEs. Though there have been interventions through the Plato mentorship programme to help develop SMMEs, there is still a high failure rate of small businesses in MCLM. The study will therefore evaluate if the Plato mentorship programme achieved its envisaged aim. A structured research instrument (questionnaire) was used to collect data through a self-administered survey. Questionnaires were distributed to the respondents by the researcher, and 100% of the questionnaires were returned for analysis. The results of the study showed that Mogale Plato mentorship programme adds value and advances small businesses and entrepreneurship. The study concluded that owners that took part in the MCLM Plato mentorship programme acknowledged that the programme was effective and increased business performance. The study showed that owners are faced with different challenges in running their businesses, which spoke volumes regarding the effectiveness of the mentorship programme. The findings also revealed that a majority of business owners benefited from the assistance received from MCLM Plato mentorship programme. The study recommends that MCLM sets up an office for mentoring individuals/groups in the municipality. This means that within MCLM, there should be a mentoring office and training twice a month that is aimed at helping business people know how to improve their businesses and manage challenges and take advantage of opportunities around them. The study also recommends that the municipality to create an incubating site for new owners/managers. The new owners/managers could share common services such as secretarial services, bookkeeping, and boardrooms / Business Management / M. Tech. (Business Administration)
