World Schools Debate Prep with AI
Practice WSDC motions, burdens, POIs, and reply speech framing.
Published ยท Updated
How does World Schools debate work, and how should a team prepare?
Two teams of three speakers each give eight-minute substantive speeches, then each team gives a four-minute reply, opposition first, delivered by its first or second speaker. Prepare by interpreting the motion: define terms, give a model for policy motions, name the stakeholders and write each side's burden. Practise every role, because first, second, third and reply speakers owe the team different things. Motions are prepared or impromptu, so also practise preparing within an hour. Offer short Points of Information aimed at a warrant, and as a general rule accept at least two.
Motion interpretation
Define the model, the stakeholders and what each side has to prove before anyone writes a speech.
Team roles
What the first, second and third speakers and the reply speaker each owe the team, and how to practise each role.
POIs and reply speeches
Points of Information that test a warrant in fifteen seconds, and reply speeches that frame the debate without new arguments.
How a World Schools round works
World Schools Debating Championships (WSDC) style has two teams of three speakers. Each speaker gives an eight-minute substantive speech, alternating from the proposition, and then each team gives a four-minute reply speech, opposition first. The reply is given by the first or second speaker, never the third.
Motions are either prepared, announced weeks ahead, or impromptu, with about an hour of preparation and no internet. Judges score style, content and strategy, so a well-organised team case can beat a collection of strong but disconnected arguments.
Start with the motion
WSDC motions are broad, so the first job is to interpret them. Define the terms, set out the model if the proposition is proposing a change, name the stakeholders, and say what each side must prove. Clear framing in the first speech shapes the rest of the debate.
- Define the key terms in a way a reasonable person would accept.
- If the motion asks for a policy, give a model: who does what, and what it does not cover.
- List the stakeholders and how the motion changes things for each.
- Write the burden for each side in one sentence.
- Identify the two or three clashes the debate is likely to turn on, and decide which speaker carries each one.
Team roles
First speaker
Sets up the debate: definitions, model, burdens and the team line, then the first arguments. The opposition first speaker also begins rebuttal.
Second speaker
Rebuts the other side's case and extends their own team's arguments with new material. This is usually the speech with the most new analysis.
Third speaker
Organises the debate into its main clashes, rebuts within each one and weighs. Responding is the main job: a third speaker may present a small part of the team case only if the first speaker announced it when setting out the team line.
Reply speaker
Gives a short, biased summary of the whole debate: where the clashes were and why their team won them. No new arguments, and no new rebuttal.
Practise each role separately. A speaker who can only do one job is a weak point when the team needs to change roles for an impromptu round.
Points of Information
Speakers on the other side can offer a Point of Information during a substantive speech, except in the first and last minute, which are protected. The speaker chooses whether to accept, and as a general rule should accept at least two. A good POI is short, under fifteen seconds, and aims at the warrant the speech depends on.
Answering POIs matters as much as offering them. Take one, answer it in a sentence, and return to your structure. Turning down every POI usually looks evasive to judges.
Prepare for WSDC with DebateLab
Use Brainstorm and case generation to map arguments for both sides of a prepared motion, and run motions under a one-hour limit to practise impromptu prep. Crossfire with the AI asking the questions is a way to rehearse taking POIs and answering briefly. Attack finds the weak links in each speaker's material before the round does.
DebateLab Sparring does not yet run the full WSDC round, and the timer has no WSDC preset, so time the eight-minute speeches and four-minute replies separately.
Frequently asked questions
How long are speeches in World Schools debate?
Substantive speeches are eight minutes, and reply speeches are four minutes. Each team has three substantive speakers and one reply speech.
What is a Point of Information?
A short question or statement offered by the other team during a substantive speech, outside the protected first and last minute. The speaker decides whether to accept it.
Can the third speaker bring new arguments?
Only a small part of the team case, and only if the first speaker announced it when setting out the team line. The third speaker's main job is to rebut, organise the debate into clashes and weigh.
Who gives the reply speech?
The first or second speaker of each team, never the third. The opposition reply comes first.
How do I practise impromptu WSDC motions?
Set a one-hour timer, prepare a case with your team, and practise each role. Then review where the team line held and where it did not.
