Empirical research has confirmed the importance of supervision and support to subordinates in improving the quality of performance. This study investigated the nature of supervision and support provided at previously marginalised school-based Grade classes of the Gauteng North District, at Gauteng Province in South Africa. To meet this objective qualitative research design was used. The subjects of the study were all purposefully selected practitioners, Head of Departments and school principals. Data was collected through observations, documents analysis and semi structured interviews (individual and focus group). The total of 33 purposefully selected participants took part in the research. Participants were selected according to the socio-economic status of their schools. It included schools from rural, semi-rural, semi urban and farm areas. To analyse the information collected, responses were grouped into categories as they appear in the practitioners’ observation template and ATLAS ti. software themes for individual and focus group interviews. The findings showed that the nature of supervision and support provided in Grade classes compromised the quality of teaching. Practitioners were also very vocal about the absence of support they get with regard to classroom practices from the School Management Team (SMT). The Head of Departments also mentioned lack of knowledge of Grade R practices, work overload and limited time as challenges that inhibit them to provide the needed support. Their concerns were also confirmed by the findings of the conducted classroom observations. The mistakes and omissions made by practitioners when carrying out Grade R daily routine activities indicated a lack of proper guidance and support. It was also confirmed during practitioners’ interviews that, practitioners worked on their own without any classroom support or guidance. The problems noted were exacerbated by the lack of professional qualification of practitioners. This study made recommendations and proposed a functional model of supervision and support that could address the challenges of poor supervision and support at Grade R classes. / Curriculum and Instructional Studies / D.
