Athletes, Substitutions & Alternates:
All athletes competing at a bid-qualifying event must be listed on the official roster as active athletes and compete on Day 1. Should a team need to make any substitutions on Day 2 at the bid-qualifying event, they will be allowed to replace a limited number of active athletes with reserve athletes for the second performance. The athletes that took the floor on Day 1 will be considered the original team members on the Worlds Roster. Any reserve athletes that take the floor on Day 2 will be considered eligible substitutes on the Worlds Roster. The number of athletes that may be replaced on Day 2 is limited: Teams may replace up to 4 athletes. This includes all Senior Open and IASF divisions.
NOTE: The team coach is responsible for communicating any replacements or substitutions from Day 1 to Day 2 to the event producer. The event producer will note any changes made from Day 1 to Day 2 on the roster that was submitted by the team. Day 2 substitutions must meet all the eligibility requirements to compete as an athlete at that particular bid qualifier representing said team.

Original Team Members
Original team members are athletes that were on the floor AND included on the official team roster associated with the event where their bid was awarded. It is important to ensure your roster is true and accurate before submitting it to the bid giving event.
