Signatory Threshold

In Model UN procedure, a signatory threshold is the procedural floor — usually expressed as a fixed number or a percentage of committee membership — that a working paper, draft resolution, or amendment must clear before the dais will accept it for introduction. Signatures indicate only that a delegate wishes to see the document debated; they do not signal support for its content, which is why thresholds are typically low enough to encourage substantive debate but high enough to prevent frivolous submissions.

Thresholds vary by conference and committee size:

• Large General Assembly committees (100+ delegates) commonly require signatures from roughly 20% of members present, though some conferences fix a flat number such as 20 or 30.
• Mid-sized ECOSOC or specialized bodies often set the bar at around 15–20% of the committee.
• Small crisis committees or Security Council simulations (15–20 delegates) frequently require only 2–4 signatories, and some crisis formats waive the requirement entirely for directives.
• Amendments usually carry a lower threshold than full draft resolutions, sometimes just a handful of signatures regardless of committee size.

The mechanics trace loosely to actual UN practice, where draft resolutions in the General Assembly are sponsored and co-sponsored by member states before tabling, though the real UN does not use a strict "signatory" category distinct from sponsorship. MUN conferences imported the distinction to teach delegates the difference between procedural willingness to debate and substantive endorsement.

Delegates should check the rules of procedure packet issued by their conference — NMUN, WorldMUN, Harvard WorldMUN, and THIMUN-style conferences all use slightly different rulesets. Under THIMUN procedure, for example, draft resolutions are typically pre-written in caucus blocs and signatory counts are handled at the approval panel stage rather than on the floor.

Failing to meet the threshold means the paper cannot be introduced, even if it commands majority sympathy — a common pitfall when delegates focus on writing rather than lobbying.
