The focus of the study was an exploration of the perceptions of secondary schools’ principals about the effectiveness of school governing bodies in Ga-Rankuwa, Tshwane West District. The main research question was formulated as follows: What are the secondary schools’ principals’ perceptions about the effectiveness of school governing bodies in school governance? The main aims were to determine how the findings of the study could add to new knowledge about the effectiveness of school governing bodies in Ga-Rankuwa and to ascertain if the perceptions of secondary schools’ principals play a role in the effective functioning of school governing bodies. A review literature worked a synthesis of perspectives on functions and roles of school governing bodies. The study examined the roles, functions of school governing bodies in selected developed, and developing countries and discussed in detail school governing bodies in the South African education system after 1994. Informed by the literature review, an empirical inquiry using a mixed method; combination of qualitative and quantitative methods to explore the perceptions of secondary schools’ principals about the effectiveness of school governing bodies in Ga-Rankuwa, Tshwane West District. Sampling of respondents was purposeful. Qualitative and quantitative methods of data gathering were used in order to produce reliable and valid results. The study involved seven (n=7) secondary schools principals who responded to a researcher-designed, pen-and-paper questionnaire and participated in semi-structured interviews. Ethical requirements were met and the identity and privacy of participants were protected. Data presented were mainly derived from documentary sources, the questionnaire and interviews. Data were analyzed, the findings presented, interpreted and the significance noted. Findings indicated that little had been documented in relation to the exploration of perceptions of secondary schools` principals about the effectiveness of school governing bodies in Ga-Rankuwa. Overall, the principals were positive about the role played by the school governing bodies; although they identified several areas in which both school governing body members and principals required ongoing training. Based on the findings of the literature and the empirical study, the researcher recommended the establishment of a special unit for the training and induction of secondary principals and newly elected members of school governing bodies to ensure effective school governance. The constraints of the study were financial. The findings of this small-scale study cannot be generalised; however, several areas for future research were identified. / Educational Leadership and Management / D. Ed. (Education Management)
