The OECD’s Development Assistance Committee (DAC) conducts peer reviews of individual members once every five to six years. Reviews seek to improve the quality and effectiveness of members’ development co-operation, highlighting good practices and recommending improvements. A DAC member since 2013, Poland has aligned its 2021-2030 Multiannual Programme with the 2030 Agenda, under the leadership of the Ministry of Foreign Affairs (MFA). Building on recommendations made in Poland’s first peer review in 2017, this review identifies opportunities for the Polish development co-operation system to work better together, programme bilateral official development assistance (ODA) more efficiently, and enhance multilateral and civil society partnerships. Recommendations include moving from annual calls for proposals to a more sustainable partnerships model, strengthening the MFA’s capabilities to co-ordinate with other actors in partner countries and better aligning Poland’s international engagement with its commitments to sustainable development.
