Our role

The students behind the opportunity.

WSDC Team Korea Qualifiers, convened at Seoul International School with the society's support.

A tournament begins long before the first speech. It takes an idea, a team, coordination, and a place for people to come together. SIS Speech & Debate Society helps make that happen, convening events and working with organizers and students to create meaningful opportunities for participation.

The kinds of outcomes the society works toward:

  • A student practices a first speech and receives useful feedback.

  • An eligible participant accesses a national-team qualifying opportunity.
  • A student organizer turns an idea into a workable event proposal.
  • Volunteers gain experience running an event.
