The organization was and is simple: INTA takes pride in its compact, non-bureaucratic structure. *  There is a General Assembly of all paying members. This meets at the annual congress and determines the general policy.

The Governing Board, composed of representatives of the various countries and chosen by the General Assembly, is the most important general administrative body. Every two years, it chooses a president *  and an Executive Committee, consisting of 15 members. In addition, there is a General Secretariat led by a General Secretary with executive tasks.

There are several different categories of members: ‘national members’ (1991: 3.5 per cent), ‘corporate members’ (1991: 63.3 per cent) and ‘individual members’ (1991: 33.2 per cent). *  The members come principally from the public sector (1991: 61.6 per cent), but the private sector is also relatively well-represented (1991: 13.9 per cent). In 1991, the proportion of designers was 11.9 per cent, but academics formed at that time only 3.8 per cent of all members. * 

Information about member numbers is difficult to retrieve. At an election in 1994, there were seven national members (Egypt, Israel, the Netherlands, Turkey, France, Taiwan and the UK) registered, 95 institutional, 50 individual and 14 honorary members; in total 740 voting members from 35 countries. *  An acquisition letter from 1999 refers to 1000 members in 47 countries.
