 Like nearly all International Science Olympiads, its problems are translated and completed in several languages and as such must be written free of any native language constraints.However, unlike other olympiads, the translations are provided by the multilingual Problem Committee, a body of experts independent of the delegates' team leaders.Because competitors could gain some advantage if they are familiar with one or more of the language groups which are the subject of some of the assignments, problems are increasingly based on some of the world's lesser known languages.
