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.

Slovenia's official development assistance to Gross National Income ratio increased from 0.16% in 2017 to 0.19% in 2021, with a temporary uptick to 0.29% in 2022. This increase was mainly due to in-donor refugee costs related to Russia's war of aggression against Ukraine. Slovenia punches above its weight as it influences decision-making in multilateral organisations in line with its priorities, notably on water and gender. Partners value its strong support to the Western Balkans, anchored in its European Union accession experience, as well as its support to demining efforts around the world. This peer review provides a set of recommendations to focus its approach, ensure cross-government co-ordination, match financial and human resources to ambitions, and build stronger relationships with partners.
