Procedures for Admission of National Member Organizations to the International Union of Psychological Science

Admission occurs following the steps detailed below.

  1. A formal petition for admission to the IUPsyS is sent to the Secretary-General of the Union by the appropriate official of the national organization of psychology. The letter requesting admission should be accompanied by the following information in English:
    • A copy in English of the national organization’s constitution, statutes, and by-laws;
    • A list of current officers.
    • A list of current members (if available) and a brief statement describing the general characteristics of the membership (their academic qualifications, occupations, representativeness of scientific psychology throughout the nation etc., stated in general terms).
    • A brief statement on the history of the organization and some of its main past and current activities.
    • Any additional information providing assurances that the organization is a truly national organization of scientific psychology, regularly established. (Where there is more than one such national organization in a country, a federation or association that includes all of them shall be eligible for national membership in the IUPsyS).
  2. After ascertaining that the above information is complete, the Secretary-General sends the petition and supporting documentation to the IUPsyS Executive Committee for review and approval.  If recommended by the Executive Committee, the petition will then come before the IUPsyS Assembly for review.
  3. The petition and accompanying information are distributed to all voting members of the IUPsyS Assembly for approval.
  4. The Secretary-General notifies the national organization of psychology of its admission to the IUPsyS, effective upon receipt of annual dues. The Membership Category is determined according to a score calculated from country resources, number of psychologists, and development of psychology in the country.  The dues are set in terms of six-category system, as follows:


National Members Score

Annual dues (2014)


0 to 199



200 to 359



360 to 599



600 to 999



1000 to 1299



1300 and over


An additional temporary category, Category O (Observer status), is permitted, involving no annual dues or voting rights.  The expectation is that Members in the Observer Category will become regular dues-paying Members in a timely manner.

Admissions material should be sent to:
