Who is eligible to attend TESMUN?

The conference is pitched at the high school level, making it appropriate for secondary school delegates and their faculty advisors rather than university teams.

Where is the conference held?

TESMUN takes place in Medellín, Colombia, which means delegations traveling from outside Latin America should plan for international connections into Colombia.

How do delegates apply?

Applications run through a recognized MUN registration platform linked from the conference's official listing, which is the same channel used for many international conferences.

What size of conference should delegates expect?

TESMUN runs at a scale that supports substantive committee work without the logistical complexity of the largest regional conferences, which generally translates into more floor time per delegate.

Summary

The Teresiano School Model of United Nations convenes high school delegates in Medellín for a multi-day simulation hosted in Colombia. The conference is positioned within the Latin American MUN landscape and operates at a scale that allows for substantive committee work without the logistical sprawl of the region's largest gatherings. For students weighing where to invest their late-summer conference budget, TESMUN offers a Colombian venue, a high school level focus, and a structured application pathway through a recognized MUN registration platform.

Why this edition matters in 2026

Medellín-hosted conferences give delegates a chance to practice multilateral negotiation in a Latin American setting, which matters because the rhythms of debate, the conventions around motions, and the expectations placed on position papers can differ meaningfully from circuits in other regions. Students who only ever attend conferences in one geography tend to develop habits that are difficult to unlearn when they move into university-level MUN or into actual policy work. The high school level designation also matters. It signals that chairs will be calibrating committee difficulty for secondary students rather than running graduate-style crisis simulations, which makes TESMUN a sensible choice for delegates building their first serious portfolio of conference experience. Finally, a Colombia-based conference is a useful data point for delegations from outside the region that want exposure to how Latin American schools approach the Model UN format. That exposure is hard to replicate by reading conference handbooks alone.

How to prepare

Preparation should start with the application pathway. The conference uses a recognized registration platform, so delegates and faculty advisors should treat the application window as the first hard constraint and work backward from it when planning travel and visa logistics for Colombia. Once a delegation is accepted, the substantive preparation work begins. Because the conference is pitched at the high school level, position papers and opening speeches should be polished but not overwritten - chairs at this level reward clarity and country accuracy more than they reward dense academic citations. Delegates should spend their preparation time understanding their assigned country's actual voting record and public statements rather than building elaborate theoretical frameworks. For traveling delegations, the Medellín location introduces practical considerations around altitude, climate, and intercity travel from Colombia's main international gateways. Faculty advisors should build buffer time around arrival and departure, especially for delegates traveling from outside the region. Finally, delegates should arrive having practiced unmoderated caucus dynamics. In a high school field of this size, the delegates who can build and hold a working bloc during unmod tend to drive the resolutions that ultimately pass.
