Checking in for a tournament is similar to checking in for an airline flight even though you may have purchased a valid ticket several weeks before. During the process, students affirm the ethics statement, parents confirm contact information, and all participants ensure they are able to access the tournament. It also helps the Tournament Administration verify that all competitors still intend to show up and compete because unexpected no shows are very disruptive to the experience of other competitors, judges, and to the tabulation system.
