National Anti-Doping Organizations (NADO)

National Anti-Doping Organizations (NADOs) are Government and/or Sports movement funded organizations responsible for:

  • adopting and implementing anti-doping rules;
  • promoting and implementing anti-doping education;
  • directing collection of samples;
  • conducting investigations;
  • managing test results; and
  • conducting hearings at the national level.


In addition to the daily assistance WADA provides to NADOs, there are currently 10 NADOs receiving direct support from WADA, including five partnership in which WADA is party to.


Established in 2015, WADA’s National Anti-Doping Organization (NADO) Advisory Group is a designated advisory group of the NADO/RADO Relations Department. The Group’s purpose is to provide expert advice, recommendations and guidance to WADA Management with respect to short term and long-term effectiveness of NADOs, their programs and activities with a regard to promoting effective doping control strategies and plans. See members and Terms of Reference.
