Oxford-Style Public Debate
Speakers for and against a motion address an audience, take questions, and close; the audience votes before and after.
- Who
- Anyone: classrooms, clubs, community events, university unions and public debate series. It is the easiest format to stage in a living room or a co-op.
- Teams
- Usually 2 vs 2 (any number works)
- Length
- 45 to 90 minutes
- Topic
- A motion, often worded "This House believes..." or "This House would...".
- Prep time
- Speakers prepare ahead of time; there is no prep time during the event.
The Oxford Union, the student debating society at the University of Oxford, was founded in 1823. Its debates borrow the House of Commons' custom of "dividing the House": members vote by walking out through a door for the ayes or a door for the noes. Public debate series such as Open to Debate (formerly Intelligence Squared U.S.) poll the audience before and after, and the side that gains the most ground wins.
Speeches in order
This is a sample program for a classroom or club. Organizers set their own times; Open to Debate, for example, gives each debater a two-minute closing.

Total speaking time: 48 minutes.
How an event works
A moderator introduces the motion and the speakers and takes the first vote. Speakers alternate for and against. After discussion and audience questions, each side closes, and the audience votes again.
Because the judge is the whole room, the best speakers talk to the audience, not past it, and treat the other side’s ideas with respect.
What it rewards
- Persuading people who aren’t debaters
- Clear structure, good examples, and a little humor
- Fair-minded engagement with the other side (audiences notice)
- Changing minds: the winner is the side that gains the most votes
How to start
- Pick a motion your audience cares about and that has two strong sides.
- Take a vote before the debate (show of hands, slips of paper, or a phone poll) and keep it secret.
- Run the program, then vote again. The side that gained more of the room wins.
- Afterward, ask a few audience members what changed their minds.
Varies by league or state
- Everything: number of speakers, times, and whether there is audience Q&A.
- How the winner is chosen: the Oxford Union counts a final division; Open to Debate uses the change between the first and second vote.
Always check the rules your tournament publishes; they win over anything here.
