In this systematic review analysis design, we explore the available peer-reviewed literature on the effect of financial management practices on service delivery in African secondary schools. Specifically, we reviewed the effect of budgeting, auditing and financial internal control on the service delivery in secondary schools. Study findings reveal that budgeting ensures effective implementation of education programs. In addition, the activities in the secondary school system are adequately planned and allocate resources apportioned to ensure effective execution and implementation. Besides, audits of school accounts result in good financial management and effective control mechanism that ensures overall operational efficiency. From the results of this review, we hereby suggest that Head teachers need to manage financial resources more responsively for effective performance and fulfilling of institutional needs, those of the teachers, students and other stakeholders of respective secondary schools. It is very crucial for school administrators and support staff in charge of finances and resource mobilization to regularly attend professional development course in order to acquire relevant financial skills and competencies required for effective management of resources in the school so as to tremendously improve on the quality of secondary schools’ service delivery.
