Since 1999, the process has consisted of two phases. During the first phase, which begins immediately after the bid submission deadline, the "applicant cities" are required to answer a questionnaire covering themes of importance to a successful Games organization. This information allows the IOC to analyze the cities' hosting capacities and the strengths and weaknesses of their plans. Following a detailed study of the submitted questionnaires and ensuing reports, the IOC Executive Board selects the cities that are qualified to proceed to the next phase. The second phase is the true candidature stage: the accepted applicant cities (from now on referred to as "candidate cities") are required to submit a second questionnaire in the form of an extended, more detailed, candidature file. These files are carefully studied by the IOC Evaluation Commission, a group composed of IOC members, representatives of international sport federations, NOCs, athletes, the International Paralympic Committee, and international experts in various fields. The members of the Evaluation Commission then make four-day inspection visits to each of the candidate cities, where they check the proposed venues and are briefed about details of the themes covered in the candidature file. The Evaluation Commission communicates the results of its inspections in a report sent to the IOC members up to one month before the electing IOC Session.
