Taking a bench abroad: the international World Schools calendar
3rd Best APDA Debater · TOC Semifinalist · Columbia Debate Society Coach
World Schools is the only high-school format with a genuinely global circuit, and most American families have no idea how much of it is open to them. This guide splits the international calendar into its two very different halves: the championships, where entry belongs to national teams, and the opens, where any school or club bench with three debaters and a plan can register. Every event below was verified against its most recent edition in July 2026. Statuses change, so treat months as “typically held” and confirm with organizers before booking anything.
The championships: national teams only
The summit is the World Schools Debating Championships: one team per nation, eight preliminary rounds (four prepared, four impromptu), held each July–August in a rotating host country. Recent editions were Hanoi 2023 (won by the USA), Belgrade 2024 (Scotland), Panama City 2025 (India def. Australia 9–0), and Nairobi in July 2026, the championship's first visit to East Africa, with Sofia, Bulgaria expected for 2027. American students get there exactly one way: the USA Debate national team.
Europe mirrors the model with EuroSDC, the continental championship under WSDC rules (2026 in Skopje; 2027 in Parma), and Asia with the Asia WSDC in Bangkok. Both run national-delegation entry: interesting to follow, not enterable from a US school.
The opens: where a US school team can actually enter
These run the same three-speaker, reply-speech, POI format and take direct entries from school and club teams. In calendar order:
January
ESDC (Eurasian Schools Debating Championship)· Robert College, Istanbul
A WSDC-format open run entirely by high-school students; the 17th edition is set for January 2027. One of the friendliest first internationals for a US team.
April
International Oldham Cup· Anglo-Chinese Junior College, Singapore
Singapore’s flagship schools event, typically ~50 teams from across Asia and beyond; the 2026 edition ran in April. Watch ACJC’s site for 2027.
April
Bluebonnet World Schools International· Spring, Texas, USA
The NSDA’s own international: all-impromptu, championship and novice divisions, with visiting international delegations. The one “international” no US team needs a passport for.
Late June
World Schools Debate Academy· Kranjska Gora, Slovenia
Half summer camp, half tournament: a residential WS academy (run by Slovenia’s Za in proti) that ends in a multi-day competition, grouped by experience level. Ideal for developing benches.
July
Prague Debate Spring· Prague, Czech Republic
WS-format summer tournament from the Czech Debate Association that draws teams and adjudicators worldwide; the 2026 edition ran July 9–12.
July
Heart of Europe· Olomouc, Czech Republic
Running since 2001 with teams from 40+ countries; a full WSDC-style schematic of eight prelims, four prepared and four impromptu. Confirm the current edition by email; the website has been unreliable.
July
Doxbridge WSDC· Online (UK-run)
The established online international: the 2025 edition ran six rounds (four impromptu, two prepared) over a July weekend at £90 per team, with national and open breaks. The cheapest international field a US team can enter.
November
EurOpen· Stuttgart, Germany
Founded 1996; explicitly invites both school teams and national delegations, first half of November. The 2025 edition ran; the website was under maintenance when we checked, so email the organizers before planning.
December
Winter Holidays Open· Zagreb, Croatia
Around 100 school teams from dozens of countries (billed as Europe’s biggest in-person schools tournament), with an open break and a novice break. Registration typically closes in late October.
The watchlist: verify before you book
Promising events whose current details we could not fully pin down. Worth an email, not yet worth a flight booking:
- Malaysia International WSDC (MIWSDC). Fifth edition announced with registration live; dates and eligibility were not yet published when we checked.
- East African WSDC, Tanzania WSDC & UAE Junior WSDC. African Debate Academy events in Nairobi (May, 90+ teams), Dar es Salaam (August), and Dubai (November). WS format per the organizer, but single-source listings; verify directly.
- QatarDebate International Schools Championship. Seven editions, English and Arabic tracks in Doha, but we could not confirm it runs 3-speaker World Schools format. Ask before entering.
- Asia WSDC (Bangkok). The Asian championship in WS format (7th edition mid-2025); primarily for national and top regional teams, and the next edition was unconfirmed when we checked.
Famous and international, but not World Schools
A warning that saves families real money: several of the world's best-known school debating competitions run different formats. The Cambridge Union's schools competitions and ICYD are two-person British Parliamentary-style events; Canada's Hart House and McGill high-school tournaments run BP and Canadian Parliamentary; Hanoi's Asian Schools Debating Championship uses Asian Parliamentary. All excellent; none of them World Schools. If your season goal is WS development (or a TOC bid back home), check the format line in the invite before anything else.
Making it work from the US
- 1
Start online. Doxbridge in July, plus the US-hosted online WS events (Penn’s invitational, Harvard’s online division, the NSDA Season Opener), give your bench an international-standard field with zero travel risk.
- 2
Pick one travel window. December (Zagreb), January (Istanbul), or July (Prague / Heart of Europe); each sits in a natural gap in the US season. One well-chosen trip beats three rushed ones.
- 3
Email the organizers early. The opens are run by debate societies and schools, not conference companies. Registration caps are real (Zagreb closes in October), responses are personal, and hybrid or composite teams are often negotiable.
- 4
Train to the judging you’ll meet. International pools apply the ordinary-intelligent-voter standard strictly: style-heavy, jargon-averse. A season of judged rounds against that standard is the actual preparation.

Common questions
Can a US school team really debate internationally without making USA Debate?+
Yes. That is the whole point of the opens. WSDC and EuroSDC are national-team-only, but ESDC Istanbul, the Winter Holidays Open, Prague Debate Spring, Heart of Europe, Oldham Cup, EurOpen, and Doxbridge all accept school or club teams directly. American teams already attend some of these: Zagreb’s recent fields have included US benches.
How do we check an event is actually World Schools format?+
Look for the fingerprints in the invite: teams of three speakers (rosters of 3–5), eight-minute substantive speeches, four-minute reply speeches, POIs, and a mix of prepared and impromptu motions. If the invite says two-person teams, fifteen-minute prep for every round, or "British Parliamentary," it is a different sport; several famous international schools tournaments are BP, not WS.
Is an online international worth entering?+
For a first international field, absolutely. Doxbridge runs a genuine multi-continent field for roughly the cost of one tank of gas, US-friendly evening hours aside, and Penn’s online WS invitational and Harvard’s online division offer international-flavored fields on US time. The judging you meet (different accents, different argument cultures, ordinary-intelligent-voter standards applied strictly) is most of what travel buys, at none of the cost.
When in the season should a US team go abroad?+
The natural windows are December (Zagreb falls after the fall US circuit and before January exams), January (Istanbul, before the spring push), and July (Prague, Heart of Europe, Doxbridge; after NSDA Nationals, when the US season is over and a traveling tournament doubles as pre-season training).
