It is important that session time (90 minutes) is distributed equally among the session participants and that adequate time (30 minutes) is left for Q&A and audience engagement. The number of participants in your session determines the length of your presentation. If there are 4 presenters, each presenter should plan to present for 15 minutes. If there are 3 presenters in your session, you can plan to present for up to 20 minutes. Discussants (if there are any) should limit comments to 10 minutes. It is the chair’s responsibility to hold presenters to the time limit.
