Abstract The importance of recruitment and selection function is a critical managerial endeavour that no organisation can ill-afford to overlook. It is even more crucial for public sector organisations in developing countries where the need for efficient and responsive public service provisioning is at the heart of most narratives framing institutional reforms. This article examines the implementation challenges of the decentralised recruitment and selection policy in the Ghana Education Service (GES) of the Upper West Region of Ghana. The results show that resource (Human, financial, and logistics), institutional and environmental factors (political interference, and non-compliance to recruitment guidelines) pose serious implementation challenges to the decentralised recruitment and selection policy in the Upper West Region. In order to generate credible, accurate, and reliable data, the study used in-depth interviews to collect primary data from twelve purposively selected respondents.
