How many teams from one school may apply to the competition?

At most two teams from any school may submit a proposal to the competition. If there are more than two teams at a given school that want to submit, the faculty coordinator for the given school will decide which two teams will submit.

What is the difference between the faculty coordinator and the faculty advisor?

The main role of the faculty advisor is to guide a specific team in its effort to put forth a strong investment strategy proposal. The main role of the faculty coordinator is to decide which two teams from a school will submit in the event that there are more than two teams that would like to enter the competition. The faculty coordinator has no role in advising any of the teams submitting to the competition. However, a single faculty member may serve as both faculty advisor and faculty coordinator.
