World Schools Debate
Teams of three debate prepared and surprise motions in long speeches, with points of information, judged on style, content and strategy.
- Who
- High school students in teams of three to five (three speak in each round). It is the format of the World Schools Debating Championships, and the NSDA offers it at its national tournament and many local ones.
- Teams
- 3 vs 3 (teams of 3 to 5)
- Length
- About an hour
- Topic
- "Motions" (This House would..., This House believes...). Some are prepared ahead; others are impromptu and announced shortly before the round.
- Prep time
- No prep time between speeches. For impromptu motions, teams get one hour from the motion's release to the start of the round (USA World Schools Debate Invitational rules), with only a dictionary and a one-volume encyclopedia or almanac.
Speeches in order
| # | Speech | Side | Time | What it does |
|---|---|---|---|---|
| 1 | P1 First Proposition | Proposition P1 | 8:00 | Define the motion, set out the proposition's case and its first arguments. |
| 2 | O1 First Opposition | Opposition O1 | 8:00 | Respond to the definition and case, and set out the opposition's case. |
| 3 | P2 Second Proposition | Proposition P2 | 8:00 | Rebuild, rebut, and add the proposition's remaining arguments. |
| 4 | O2 Second Opposition | Opposition O2 | 8:00 | Rebuild, rebut, and add the opposition's remaining arguments. |
| 5 | P3 Third Proposition | Proposition P3 | 8:00 | Mostly rebuttal: organize the clash and answer the opposition. |
| 6 | O3 Third Opposition | Opposition O3 | 8:00 | Mostly rebuttal: organize the clash and answer the proposition. |
| 7 | O Reply Opposition Reply | Opposition O1 or O2 | 4:00 | A short, fair overview of the debate from the opposition's view. Given by the first or second speaker. |
| 8 | P Reply Proposition Reply | Proposition P1 or P2 | 4:00 | A short, fair overview of the debate from the proposition's view. The last speech of the round. |
Total speaking time: 56 minutes.
Points of information may be offered only by the other team, only during the six eight-minute speeches, and not in the first or last minute. The speaker may accept or decline. Reply speeches have no points of information.
Protected time: the first 60 seconds and the last 60 seconds of each speech that allows them. A point lasts about 15 seconds at most.
How a round works
Speeches alternate between the proposition and the opposition, three per side, then each side gives one reply speech, the opposition first. While the other team speaks, debaters may stand and offer a point of information, a short question or statement the speaker can accept or decline.
World Schools favors arguments of principle and well-chosen examples over stacks of quoted evidence, and it rewards a team that works together across all three speakers.
What it rewards
- Style, content and strategy, weighted 40%, 40% and 20% on the ballot
- Arguments about principle and real-world examples, not quoted evidence cards
- Teamwork across three speakers
- Taking and answering points of information well
How to start
- Practice an eight-minute speech built from two arguments, each with an example.
- Practice impromptu prep: one hour, a team of three, paper only.
- Offer and answer points of information in practice: one short sentence, then sit down.
- Learn the reply speech: it summarizes the debate’s main clashes; it is not a fourth constructive.
Varies by league or state
- Prep for impromptu motions: one hour at the USA World Schools Debate Invitational and the World Schools Championships; local tournaments sometimes use less.
- Materials: international and NSDA invitational rules forbid electronic devices in rounds except a phone used only as a timer; local tournaments may differ.
- The mix of prepared and impromptu motions differs by tournament.
Always check the rules your tournament publishes; they win over anything here.
