The International Association of Applied Psychology is the oldest international association of psychologists. Its official languages are English and French. Founded in 1920, it now has more than 1.500 members from more than 80 countries. Its mission is succinctly stated in Article 1 of its Constitution:
...to promote the science and practice of applied psychology and to facilitate interaction and communication about applied psychology around the world.
The Association distinguishes five membership categories: Full Members, Fellows, Student, Honorary and Alliance Members.
- Officers of IAAP (President, President-Elect, Past-President, Secretary General, Treasurer) are elected every four years by the Board of Directors which meets biennial.
- Board of Directors: Members are elected on the basis of their scientific achievements, commitment to IAAP, and their dispersion over the world's regions. Presidents of each IAAP division are also members of the BOD. Hence, there is a double aim, representation by regions and by divisions.
- In the past, General Meetings: took place every four years in connection with each International Congress of Applied Psychology. In 2006 they were cancelled in the new constitution and the general membership is reached via a) a general email distribution list, b) e-mail distribution lists by divisions, c) an online voting procedure for the President Elect.
Most of the Association's work is achieved through its Divisions, Standing Committees, and Task Forces. The Divisions pursue the scientific concerns of IAAP members working in various sub-fields of applied psychology. In 2012 IAAP had recognized eighteen Divisions:
- Division of Organizational Psychology
- Division of Psychological Assessment and Evaluation
