The team captains are usually chosen by the team members. They will nominate some people and they will have a vote. The person with the most votes will become the captain of the team.

You can generally have any number in a team. Competitors are rotated on a team for each show to allow everyone a chance to participate. An average team will have around 8-14 people. For example, on an Intercollegiate Horse Show Association (IHSA) team, the number of members can range from a dozen to 100! Usually there is a point squad that members compete to be a part of, and it is this group of riders that contribute to overall team points.
