Requesting new working language*
Before Jan 31, 2026
- A new working language means a language that was not present in the previous IOL. Please, note that countries can ask for any language. Asking for a particular language (e.g. English) does NOT give an advantage during the contest – all language versions are equal.
The list of the IOL 2025 working languages can be seen on the IOL 2025 working languages page. Please, make sure that you have read through the Working language(s) selection page carefully before requesting a new language.
