The World Schools Debating Championships (WSDC) is a truly global competition for high school debaters. The Championships take place each year in a different country, hosted by a national debating body. Past venues include Peru, Qatar, Seoul, Athens, Cape Town, Bangkok, Singapore, Stuttgart, and in 2017 Denpasar, Indonesia.

All debates take place in English. Each country can submit a squad of 3-5 eligible students to debate social, moral and political issues. There are currently between 50 and 60 nations that meet annually.
