Bulgaria established cooperation with OECD in the early 90s of the 20th century, with the interaction taking place through the participation of the countries in separate working bodies of the organization and within the framework of separate thematic initiatives and programs. The country is an active participant in the OECD regional program for South-Eastern Europe and engages in its statistical and information reporting systems. Undoubtedly the issue of Bulgaria's membership in the OECD is more than topical and is of particular importance for the country in its struggle for achieving the highest possible results in its goals for reforms and the welfare of its citizens after the completion of socialist rule. This is the reason why in 2007 Bulgaria officially expressed its desire to obtain the status of a member in the organization and in 2022 it officially received an invitation. The analysis sets itself the limited goal to study Bulgaria on its way to membership in the organization, to give a vision of what the OECD represents, and to draw up proposals and key recommendations for the country for accelerated and maximally effective membership.
