This study explored the views and experiences of School Management Teams (SMTs) when implementing Integrated Quality Management System (IQMS) in three primary schools in the Nkangala Region of the Mpumalanga Province, South Africa. A qualitative research approach was adopted and the data were collected by means of semi-structured interviews and document retrieval in schools. The data were then analysed by the constant comparative method. All the participants in this study expressed the view that IQMS is a teacher appraisal system with a potential to develop educators in schools provided both evaluators and evaluatees are honest with the evaluation process and are able to identify their areas of development. However the experience of the principals and deputy principals with the implementation of IQMS in schools reveals that educators inflate their scores and do not identify areas where they need development. The Development Support Groups (DSGs) do not conduct authentic evaluation since they serve the purpose of helping educators to qualify for salary progression. Participants recommended external evaluation as a solution to subjective ratings since external evaluators have a potential to provide objective and credible evaluation because they are unfamiliar with educators and do not experience the pressure to maintain collegiality in schools. A key recommendation is that the Department of Education should conduct effective training for the stakeholders involved with the implementation of IQMS in schools.
