The General Assembly is the supreme decision-making body of the Association, and is convened by the President at least once a year, usually during the Frankfurt Book Fair.

The General Assembly consists of Delegates from IPA's Full Members, who are normally appointed for a term of three years. IPA Affiliate and Associate Members may send non-voting observers to the meetings of the General Assembly.

The General Assembly defines the general strategy of the Association and elects the Directors serving on the Executive Committee, as well as other unpaid Officers, including the chairpersons of any working committee.
