The rules that actually matter
- Two students on each side: Pro agrees with the topic, Con disagrees.
- Three times during the debate there is a "question time" where both sides ask each other questions directly (3 minutes each).
- Each team gets 3 minutes of planning time to use whenever they want during the debate.
- In the last speeches, each side has to explain why their points matter MORE than the other side's — not just repeat them.
- If a team uses a fact or a quote, they have to be able to show it to the other team or the judge.

How Public Forum rounds are judged
- Written for a lay/citizen judge — you don’t need jargon, but strong warrants still win.
- Weigh impacts explicitly; Public Forum expects framework and weighing in summary/final focus. Common mechanisms are scope, severity, magnitude, and probability.
- When both teams weigh with different mechanisms, look for "meta-weighing" — an explicit argument for why their weighing standard should come first — rather than just picking a mechanism yourself.
- Crossfire answers count as part of the round — arguments and concessions made there are fair game.

Frequently asked questions
How long is a Public Forum debate round?
About 45 minutes of speaking and questioning, plus 3 minutes of prep time per team that they can use whenever they like during the round.
What is crossfire in Public Forum?
Crossfire is a period where both sides question each other directly rather than one side asking and the other answering. There are three in a round — after the first speeches, after the second speeches, and a grand crossfire involving all four debaters.
What makes Public Forum different from Policy or Lincoln-Douglas?
It is shorter, argued in teams of two on current-events topics, and written to be judged by a non-specialist. Clarity and persuasion count for more than speed or technical jargon, which is the opposite of how Policy rewards speed.
Do you have to share evidence in Public Forum?
Yes. If a team uses a fact or a quotation, it must be able to show that evidence to the other team or to the judge on request.
What is weighing in Public Forum, and why does it decide rounds?
Weighing is explaining why your impacts matter more than your opponents’ — comparing magnitude, probability, timeframe and reversibility rather than restating your case. In the summary and final focus, a side that weighs usually beats a side that only repeats.
How many speeches are in a Public Forum round?
Each team gives four speeches — a constructive, a rebuttal, a summary, and a final focus — with three crossfire periods interleaved between them.
