Since the foundation of the ISSCT in 1924, the Society's Constitution has significantly evolved to improve its activities and operations.

The two major improvements to the Constitution in more recent years have been in 1986, with the setting up of an Executive Committee to ensure continuity and management during periods between Congresses, and in 1995 with the establishment of a Secretariat. Other minor changes have been effected at various Congresses.

At the seven Congresses, the Society has taken several further strategic initiatives to better respond to members' expectations. The most important changes in 2001 have aimed at greater involvement of the Executive in the future management and control of Congress, and improved communication with Councillors and Affiliated Societies through changes in the appointment of Councillors. The latest changes have been the setting up of a Management Commission, the appointment of a Editor and Security measures for members attending Congresses and Workshops. In Brazil among the strategies adopted is the involvement of young technologists in ISSCT, reduction of cost of attendance at congress, possibilities of organising congresses by ISSCT and opening the society to African industries which hold promises for the future.

Those aspects of the ISSCT Constitution which constitute the Society's Policy, and details of the Procedures to run the Society's activities according to the objectives of the Constitution, have also been spelled out in three documents which can be accessed on this site. An Operations Manual of the Technical Program Committee has been prepared. It defines its roles and responsibilities and spells out in detail the procedures associated with the organisation of the technical program of an ISSCT congress and of ISSCT workshops. At the XXVIII Congress in Brazil a Congress Operations Manual has been adopted to better define the relations between ISSCT and the Congress Organizing Committee as well as the commitments and responsibilities of both parties.

At the XXVIII Congress in Sao Paulo, amendments were made to the Constitution. A revised consolidated version has been approved and is available on this website.
