How to Choose the Right Format
- Identify your goal – Are you aiming for a law career (Moot Court), improving public speaking (Public Forum), or mastering policy research (Policy Debate)?
- Assess time commitment – Policy and Lincoln‑Douglas require months of prep; parliamentary and extemporaneous demand less.
- Consider team dynamics – If you thrive in collaborative environments, choose a team‑based format; if you prefer solo performance, Lincoln‑Douglas or Extemporaneous may suit you.
- Check competition availability – Local schools may only offer certain formats; international tournaments may require BP or WS.
- Match your audience – For community outreach, Public Forum’s lay‑friendly style works best; academic conferences may favor Policy or World Schools.
