The third Online Olympiad in Linguistics started on Friday, January 29 (7:00 am^UTC) and ran until Monday, February 1 (10:00 pm^UTC). Appeals could be submitted until February 7.

Secondary/high school students from any country were eligible to participate. Participation required prior registration. Everyone who had registered could begin working on the problems at any time during the contest period. From the moment a contestant first saw the test, they had 4 hours and 30 minutes to work on the problems and type in their answers. (Less time was available for those who started the test after 5:30 pm^UTC on February 1.) Explaining one’s answers was not required in this year’s contest.

The test consisted of four problems of varying difficulty. Two of the problems were interactive, and the other two featured audio and video. The problems were self-sufficient—one didn’t need to have any prior knowledge of linguistics or languages to participate (apart from one’s chosen working language).

This year’s problem set was available in English, Simplified Chinese, Czech, French, German, Indonesian, Japanese, Korean, Polish, Brazilian Portuguese, Romanian, Russian, Spanish, and Ukrainian. Contestants were able to specify their working language during registration as well as update their preference in the contest area before sitting the test.

During the contest, participants were required to work individually and were prohibited from searching for anything relevant to the problems on the Internet. This year, however, it was allowed to use word processors, graphics editors, or spreadsheets.

The 2021 Olympiad saw the participation of around 700 students from 35 countries. The results of the competition have been published. Certificates of award and participation can be downloaded from the contest area.
