Who does what?

Protecting clean athletes by fighting against doping is a top priority for the IOC, which has established a zero-tolerance policy to combat cheating and to make anyone responsible for using or providing doping products accountable.

The World Anti-Doping Agency (WADA) is an international, independent organisation monitoring and regulating the global fight against doping through the World Anti-Doping Code (the Code), and is responsible for monitoring the implementation of and compliance with the Code by its signatories. The Code works in conjunction with five International Standards. To learn more, click here.

As the Olympic Movement governing body, the IOC makes the Code mandatory for the entire Movement. During the Olympic Games, it oversees all doping control and testing processes in compliance with the Code regulations. However, the IOC is striving to make all these processes independent. Since the Olympic Games Rio 2016, sanctioning has been handled by the Court of Arbitration for Sport (CAS) and its Anti-Doping Division. The creation of an independent testing agency is also underway.

Future Olympic Games Integrity: A shift to more intelligent testing

The number of tests conducted during the Olympic Games has increased over the years: up from 3,600 in Athens to over 5,000 in London and Rio. While this increase demonstrates the IOC's commitment to ensuring that athletes play fair, there is a greater shift towards using a more intelligent testing strategy through more targeted out-of-competition tests.

In order to protect clean athletes and increase the efficiency and effectiveness of the fight against doping for the Olympic Winter Games PyeongChang, the IOC will require the assistance of NOCs in this process.

NOCs will be requested by the IOC to help locate all athletes, i.e. all athletes currently in a whereabouts system and those who are not part of a whereabouts system, through accurate rooming lists (ref. to template below) for those living in the Olympic Village and addresses for those living outside. The information needs to include sufficient details (such as block and room number in specific Olympic Village and place of training), so that they can be easily located from the date of the opening of the Village (1st February 2018) up to and including the date of the Closing Ceremony (25thFebruary 2018). NOCs should ensure athletes who are part of a registered testing pool realise the importance of full compliance with whereabouts requirements. This information must be provided in electronic format on the designated template in English.
This template is available here.

NOCs may decide:

  • not to provide a rooming list if all their athletes are completing good whereabouts, or
  • to provide rooming lists on just those not on whereabouts, or
  • to complete a rooming list for the whole team, for practical purposes, including the addresses of those staying outside the village.

The rooming lists should be emailed to If PyeongChang Doping Control personnel have difficulty locating an athlete selected for testing then the relevant NOC’s system for providing location information will be reviewed by the IOC. For those athletes not on a whereabouts system, in specific cases, the relevant IF or NADO may be asked to include athletes in their formal whereabouts system.
