Format
IPDA primarily utilizes a one-on-one debate format in which one debater takes the side of the affirmative where they have the burden of advocating and proving the resolution. The other debater takes the side of the negative where they have the burden of refuting the affirmative's case. For each round, the two debaters are given five possible resolutions. The negative begins the topic selection by striking one resolution, then the affirmative strikes one resolution. The negative strikes again. Thus, the affirmative has two resolutions to choose from. The affirmative then strikes one of the remaining resolutions, selecting the other as the topic for the round. After the topic has been selected, both debaters have thirty minutes to prepare a case.
The round itself has a maximum length of 26 minutes, divided as follows:
Affirmative constructive speech (5 minutes)
Negative cross-examination of affirmative (2 minutes)
Negative constructive speech (6 minutes)
Affirmative cross-examination of negative (2 minutes)
Affirmative rebuttal (3 minutes)
Negative rebuttal and summary (5 minutes)
Affirmative summary (3 minutes)
IPDA also offers a team format of public debate. Several tournaments will be offering this format during the 2011-2012 competitive season. Check the IPDA website for future tournaments offering this option.
