The number of National Member Bodies making up the International DanceSport Federation (WDSF) stands currently at 92. After IDSF membership quadrupled between 1970 and 2010, it is projected to surpass 100 by 2012.
The WDSF Membership Commission is very active, fostering national organisations in areas where the development of DanceSport lags behind and assisting them with the education of trainers and judges. In some countries, WDSF trainers work directly with the athletes in order to bring them closer to the international levels.
One national governing body per country can become an WDSF National Member Body, provided it fulfils all requirements for membership as set forth in the WDSF Statutes. Provisional membership can be granted by WDSF to national organisations that satisfy these requirements only partially.
The World Rock 'n' Roll Confederation (WRRC) and the United Country Western Dance Council (UCWDC) are Associate Members of WDSF. These organisations have aims and objectives that are deemed compatible with those of WDSF. As Associate Members they bring their own sizable communities to an ever growing global sporting movement and promote DanceSport together with WDSF.
In 2008, the International Paralympic Committee (IPC) has entered into a formal co-operation agreement with WDSF to jointly develop and promote Wheelchair DanceSport, and to work towards establishing a single international governing body including Wheelchair.
With the implementation of the WDSF Vision 2012 to commence in the foreseeable future, several other organisations have applied for Associate Membership in recent months.
The title of Honorary Member is bestowed upon persons who have rendered outstanding services to DanceSport and to WDSF. Former IDSF Presidents Otto Teipel, Detlef Hegemann and Rudolf Baumann are Honorary Presidents, former Presidium Members Léon Léonard and Heinz Spaeker are Honorary Members of WDSF.
