This article studies USSR's unique experience in recognizing credentials issued by foreign educational institutions. It pays particular attention to the special circumstances of the country's involvement in education internationally in this respect. Because its definitions of basic terms in higher education did not correspond with those of its Western partners, cooperation between the USSR and foreign countries was mostly limited to UNESCO's standards, as well as bilateral agreements with "friendly" states. In addition to analyzing the evolution of its legal aspects, the authors also study the evolution of the administrative apparatus for recognizing foreign degrees. Beginning in the 1970s, special units of Patrice Lumumba University and the Scientific Research Institute of Higher School Problems have made important contributions in this regard. The authors consider cooperation between the USSR and the leading international organizations, such as UNESCO and the Council of Europe, as well. At the same time, they also study the Soviet Union's first steps in recognizing foreign educational standards in light of changes in the international political climate. In short, the article discusses the challenges of recognizing foreign higher education qualifications in the Soviet Union as well as the institutions charged with the task from 1950 to the early 1990s.
