The International Association of Applied Psychology (IAAP) was founded in 1920 to advance knowledge about applied psychology, and it is the oldest of the international psychology member associations. The International Union of Psychological Science (IUPsyS) is older, founded in 1889, but it is an international organization of psychological societies. The IAAP is a member organization with over 3,300 individual members from more than 80 countries. In order to sustain an international membership, the organization's dues structure allows for reduced and subsidized dues for individuals from developing countries and those who for other reasons cannot afford the standard dues.
