The Union consists of National Member organizations, not more than one National Member coming from any one country. An organization may become a National Member of IUPsyS if it is a National Society of Psychology, regularly established, a coalition of National Societies, or, alternatively, a national Academy of Science, National Research Council, or similar organization.
The term ‘country’ shall be understood to include dominions, protectorates, and nonautonomous territories in which independent scientific activity in psychology has been developed. Federated states shall be considered single countries (IUPsyS Statutes, Article 9, Section II).
