SIS Speech & Debate Society
Develop your voice.
Create opportunities.
Take the stage.
We bring students together to think critically, speak with purpose, and turn ambition into participation. Through training, student-led events, and national and international competition pathways, we help ideas become opportunities.
Based at Seoul International School. Connecting students across schools.
Our role
The students behind the opportunity.
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.
