Background: Voluntary organisations for professional evaluation (VOPEs) have proliferated across the African continent, seeking to contribute to building effective national evaluation systems (NESs) that enhance development planning, implementation and appraisal.Objectives: A study commissioned by the Centre for Learning on Evaluation and Results - Anglophone Africa (CLEAR-AA) and the African Evaluation Association (AfrEA) in 2021 highlights key strengths and challenges faced by African VOPEs in their quest to help strengthen NESs across the continent.Method: The study was qualitative by design, employing document analysis, key informant interviews and focus group discussions with selected VOPEs across Africa.Results: While African VOPEs have proliferated in number, they take different forms, and their focus tends to be shaped by their respective national contexts. A key challenge for African VOPEs is internal human and financial capacities, while the external environment within which these national evaluation associations operate also presents risks such as co-optation and opportunities such as networking and resources.Conclusion: This article argues for the need for African VOPEs to improve their internal financial and human capacity, thereby enabling these professional associations to endeavour to contribute to strengthening the supply and demand sides of NESs, as well as refining their advocacy to reflect Africa-centred evaluation approaches and criteria.
