All debates in the championship are in English. This is for practical reasons, but it means that many countries debate in what is for them a foreign language. This has not stopped a number of these teams being very successful. China and India have won one world title each. Pakistan has reached the Grand Final twice; while the Philippines, Argentina, Peru, Greece and Israel have all reached the semi-finals. Special awards have been introduced for the highest-ranked teams made-up of English-as-a-second-language (ESL) and English-as-a-foreign-language (EFL) speakers.
