Exploring the Extent of State-Mission Partnership in Missionary Public Senior High Schools (MPSHS) in Greater Kumasi

State–mission partnerships have long shaped the development and management of education systems in Ghana, particularly within Missionary Public Senior High Schools (MPSHS) where the responsibilities for policy direction, administration, and resource allocation are shared between the government and religious bodies. Despite their historical contributions, growing concerns persist regarding the effectiveness of this collaboration. As such, this study aimed to explore the extent of state-mission collaboration and the contemporary implications of this partnership for MPSHS in Greater Kumasi, Ghana. Using a qualitative approach, the study employed a case study design. The study employed purposive sampling to select 20 participants who were interviewed with the aid of an interview guide. The data was thematically analysed without the aid of a computer software. The study found that leadership decisions, infrastructure development, student admissions, and disciplinary measures are all handled collaboratively; and the partnership continues to encourage discipline based on religious beliefs. The partnership improves academic quality through state-supported staffing, mission-based moral guidance, and it improves infrastructure through joint contributions. However, challenges, such as inadequate funding, bureaucratic delays, role conflicts, low teacher motivation, resistance to reforms, and poor maintenance culture, counterbalance these benefits. The study concludes that while state–mission collaboration in MPSHS is beneficial, its effectiveness is constrained by role ambiguity and weak accountability, implying the need for clearer governance structures and strengthened coordination among key stakeholders to ensure sustainable and balanced school management.
