There is no personal membership. The association is governed by a General Assembly, which meets once every year, and consists of one representative from each National Member, and Regional Member,as well as the Chairs of Working groups and Honourary members.
Representative is the key word.
Since IMIA will only accept one society as national representative in any country, a candidate association or society must be able to convince the General Assembly, who decides on the admission of National Members, of its qualities in this respect. An appropriate national society applying for membership may apply for Corresponding Member Status in IMIA during the preparation of an application for a maximum of three years. Representatives from countries which are not members of IMIA, but are planning or engaged in significant activities in medical informatics, may be accepted by the General Assembly as Observer at IMIA meetings for a maximum of three years. The amount is determined by the size and economic status of the membership country. If theses dues have not been paid for two years, the General Assembly will determine whether the membership should be terminated.
