This study investigated the professional occupational competences of Technical and Vocational Education and Training (TVET) lecturers in Gauteng Province, South Africa. Specifically, the study examined the management and support intervention systems for lecturer development in five colleges. A multi-case study design was adopted for this qualitative research study. Purposive sampling technique was used to select fifteen participants. Semi-structured interviews were utilized to gather data, whilst thematic analysis was applied for data analysis. The findings reveal that colleges have inadequate professional occupational competence interventions in place, and that they lack the necessary management and administrative skills to facilitate effective professional occupational competence development for their lecturers. The study recommends that TVET college managers be trained appropriately to champion and model organizational learning in their institutions.
