International Tennis Integrity Agency - International tennis organisation
The International Tennis Integrity Agency (ITIA) is the organisation responsible for safeguarding the integrity of professional tennis worldwide. It was established following a comprehensive review of integrity in the sport. The ITIA assumed responsibility for administering the Tennis Anti-Corruption Program on its formation and for the Tennis Anti-Doping Programme on 1 January 2022. In addition to prevention, education and drug testing activities, it gathers intelligence and investigates competition manipulation, most notably match fixing in tennis. It has the ability to impose fines and sanctions, and ban players, umpires, and other tennis officials from participating in sanctioned tournaments. The ITIA is an initiative from the International Governing Bodies (IGBs) of professional tennis: the ITF, ATP, WTA, and the four Grand Slam tournaments (the Australian Open, French Open, Wimbledon and US Open). The organisation assumed the responsibilities of ITF's Tennis Integrity Unit (TIU, 2008–2020). The ITIA is legally independent of the IGBs and makes its own decisions on investigations and prosecutions. In this respect it is unusual in global sports.
