Augmind StudioPF and LD are the two biggest high-school debate formats — roughly 40% and 25% of NSDA competitors respectively — and for a new program the choice shapes everything: recruiting, coaching load, judge recruitment, even which students stick. Here’s the comparison we’d give a program director, followed by a recommendation that fits most new programs.
The formats in one sentence each
Public Forum: two-person teams debate a monthly current-events resolution in plain language a parent-judge can follow. Lincoln-Douglas: one student defends a value framework — “I value justice, my criterion is…” — on a two-month resolution, and rounds are won by making your framework the lens the judge uses.
Side by side
| Dimension | Public Forum | Lincoln-Douglas |
|---|---|---|
| Team size | 2v2 — partners share the load; nobody stands alone | 1v1 — the student owns every speech |
| Topic cadence | New resolution monthly (NSDA); current-events flavored | New resolution every two months; values/philosophy flavored |
| What wins rounds | Evidence quality, clean line-by-line, weighing a lay judge can repeat | Framework control — whose value/criterion becomes the lens — plus weighing under it |
| Judges | Built for lay judges (parents); plain language is rewarded | More technical judge pools, varying by circuit |
| Evidence load | Meaningful weekly cutting, shared across the partnership | Moderate; reading philosophy matters as much as cutting cards |
| Speech lengths | Short speeches (4-minute constructives) + crossfires — beginner-friendly stamina | Longer solo speeches with heavy time asymmetry (the 1AR is famously hard) |
| Student fit | Social, current-events kids; students who want a partner | Independent, philosophical kids; students who like owning the whole round |
Our recommendation for a new program
- Start with PF if your room is new to debate: partners halve the fear, monthly topics keep research fresh, and your parent-judge pool can actually judge it. The skills — tag / warrant / impact, line-by-line coverage, weighing — transfer to every other format.
- Choose LD when you have independent, philosophically-inclined students and access to circuits with experienced judges — or a coach who loves framework debate enough to teach it well.
- Middle school: run your league’s PF-style or Parli-style event, and spend most practice time on structure and impromptu anyway (our 12-week arcs show the split).
Whichever you pick, the practice loop is the same
Rounds are won in the weekly loop: isolated reps (one refutation, one weighing comparison, one crossfire answer), recorded, scored against an anchored rubric, with one next step per student. Our HS rubric pack includes the drill rubric built for exactly those reps — and the drill bank has the reps themselves.
Frequently asked questions
Which debate format is best for middle school?
A PF-style format (or your league's local equivalent — some circuits run Parli or modified PF). Everyday topics, a partner, short speeches, and lay-judge norms match middle-school attention and confidence. Save LD's framework debate for students who already hold structure comfortably.
Can one program run both PF and LD?
Established programs do; new programs shouldn't. Each format is its own coaching load — topic prep, drills, judge adaptation. Pick one for year one, get a full season of reps, add the second when a student pulls toward it.
What about Policy, Congress, and Big Questions?
Policy is the deepest format — season-long topic, heavy research, fast technical delivery — best joined where local schools already sustain it. Congress rewards prepared floor speeches and suits big squads. Big Questions (science/philosophy resolutions) is a good LD on-ramp. None is the right first format for a brand-new program.
How should practice reps be graded in either format?
Score full speeches on a five-dimension debate rubric (argumentation, clash, evidence, delivery, signposting), and isolated drills on a pattern-execution rubric so the target move doesn't get averaged away. Both are in our free rubric packs with full band descriptors.
