At recent assemblies IBSA has also held a blind sports conference.
The assembly's wishes are carried out through the bodies set out in IBSA's Statutes (Constitution) and Internal Regime Regulations (By-laws). The main bodies are:
Comprising the President, the Vice-President, the Secretary General,
the Treasurer and five members-at-large. The IBSA Executive Director is a non-voting member of the board.
IBSA also has five regional committees:
The regional committees' mission is to organise sports events for blind and partially sighted sportsmen and sportswomen in IBSA sports, as well as implement and consolidate the overall goals of the federation in their region, as they are laid down by the governing bodies.
Each sport has a committee in charge of developing the sport, ensuring a strong competition calendar, setting the rules of the sport, laying down the sports technical conditions for events, plus many other matters related to their sport.
