Public Forum PF
NSDA U.S. high school format. Resolution rotates monthly. Evidence-driven, two-on-two, four-minute speeches.
Public Forum is the NSDA's flagship high-school format and the most widely competed event in U.S. high-school debate. The resolution rotates roughly monthly during the season; teams debate the same topic for a few weeks before it changes. Two teams of two debaters, four constructive speeches followed by crossfire, summary, and final-focus speeches.
PF is evidence-heavy. Cards (cited evidence from named sources) are mandatory in constructive speeches and across rebuttals. The format rewards clean evidence comparison — which study has a larger sample, which is more recent, which controls for confounds.
Crossfire periods between speeches are where strategy lives. The format is fast but not Policy-fast; clarity matters more than speed. Final focus is purely weighing — no new arguments, just a closing brief on why your impact outweighs.

How judges score it
- Evidence quality (recency, source, methodology) is decisive.
- Crossfire performance is judged — not just speech delivery.
- Summary and final-focus speeches must weigh, not re-argue.
- Lay judges are common — clarity beats jargon.
- Dropped arguments in summary are usually treated as conceded.
What wins this format
- Two strong cards beat five mediocre ones.
- Crossfire questions that lock the opponent into a position they then have to defend.
- Summary that collapses to two impacts and weighs them.
- Final focus that gives the judge a one-sentence ballot story.
What loses this format
- Card spam without analysis — judges discount cards you do not explain.
- Aggressive crossfire (yelling, talking over). Penalized.
- New arguments in final focus.
- Reading evidence faster than the judge can flow.
