The policy of the Association shall be to attain these purposes through scholarly publications, workshops, international conferences, the establishment of chapters, and other such activities consistent with the objectives of the Association as may be directed by the Council. The primary function of the Association is to act as a federation of its institutional members to accomplish the above goals. It shall also be the policy of the Association to insist upon the highest standard of scholarship and service from its members.

The Association is a not-for-profit organization.

3.3. Corporate Membership

Besides acting primarily as a federation of its institutional members, the Association also provides services for its individual and corporate members.


4. Organization

4.1. The association is governed by the council , whose elected members are:

  1. President
  2. President-elect
  3. Treasurer
  4. Secretary
  5. Four Council members at large (Vice-Presidents)
  6. One representative of each Society/Chapter, institutional and corporate member

The principal editors of IFSA journals shall be invited to all Council meetings, and shall be included in all Council correspondence. Members of the Council must be elected members of the Council and the appointed representatives of institutional members, usually the President of the Institutional Member or his/her designated delegate, or a delegate of a corporate member.

4.2. The policies of the Council are carried out by the Excutive Board. The Chairman of the Executive Board is the President-elect. The President, the President-elect, the Treasurer, and the Secretary are ex-officio members of the Executive Board.

The President may appoint additional members to the Executive Board with the concurrence of the Council; such concurrence shall be by direct vote, by mail or by email.

4.3. The Council decides the rules of accepting new members. The Council appoints such other committees as it finds necessary to carry out the business of the Association or to further its objectives.

Vice-Presidents shall preferably chair these committees. There shall be at least two such committees:

  1. Meetings Committee;
  2. Membership and Chapters

4.4. Groups of individual members may form chapters of an Institutional Member. These chapters may be formed on a territorial basis, they may be special-interest groups or they may be a combination of both. They may either adopt the Association's Constitution and By-Laws or design their own. A chapter has to be approved by an Institutional Member before the chapter is officially established. Thus chapters belong to an Institutional Member and hence indirectly belong to IFSA. But they have no representation in the IFSA Council except indirectly by the Institutional Members to which they belong.
