Worlds Schools Debate (often called the World Schools style or WSDC format) is the competitive debating format associated with the World Schools Debating Championships, first held in 1988. It is designed to blend features of British and Australasian parliamentary traditions, making it accessible to national teams from very different debating cultures.
Each round features two teams of three speakers — the Proposition (sometimes called Government) and the Opposition — arguing a single motion. Each debater delivers an eight-minute substantive speech, followed by a four-minute reply speech delivered by either the first or second speaker on each side (the Opposition reply comes first, then the Proposition reply). During substantive speeches, opponents may offer Points of Information between the first and seventh minutes; the speaker chooses whether to accept them.
Motions alternate between prepared topics, released weeks in advance, and impromptu topics, released one hour before the round. Subject matter ranges across international relations, domestic policy, ethics, economics, and social issues, which is why the format is popular with Model UN delegates and IR students looking to practice argumentation on policy questions.
Judging uses a structured rubric, typically weighting content (40%), style (40%), and strategy (20%), with reply speeches scored at half marks. National teams compete at WSDC, organised since 1988 with rotating host countries; past champions include Australia, Singapore, Scotland, England, Pakistan, Canada, and others.
Distinctive features compared to other formats:
- National team composition rather than school-based teams at the international level.
- A whole-team burden to defend a consistent case, rather than the four-bench dynamic of British Parliamentary.
- Strong emphasis on engagement and clash rather than purely technical role fulfilment.
- Use of Points of Information as a live interaction mechanism.
The format is also widely used at regional championships and is increasingly adopted in secondary school circuits worldwide.
Example
At WSDC 2019 in Bangkok, Canada defeated England in the grand final on a motion concerning democratic backsliding, with each side fielding three speakers in the standard World Schools format.
