National certificates of language proficiency

A National certificate of language proficiency,or a YKI certificate, is a certificate of language proficiency for adults that allows you to prove your language skills in an officially recognised way. YKI examinations evaluate skills in common language in practical situations, meaning that they require no knowledge of specialty language or specific industry jargon.

National certificates of language proficiency and the coronavirus

We are currently facing exceptional circumstances due to the coronavirus situation. For this reason, YKI language proficiency tests will not be organised between 18 March and 13 April 2020.

If you have signed up for an YKI exam taking place within the period mentioned above, the educational institution hosting the test will contact you to provide directions on how to proceed. In general, all registrations are moved to the next available test date of the same language and level. Please wait for further instructions from the test organiser.

The intermediate level Finnish exam scheduled for 23 May 2020 may take place depending on the overall health situation in Finland at the time. The Finnish National Agency for Education will provide more information on the issue on this web page between 13 and 14 April 2020. Follow this page to stay up to date!
