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.

The YKI system for National certificates of language proficiency is the Finnish government's official system for language proficiency testing. A YKI certificate can be used for many purposes, such as:

  • applying for a job or a university
  • applying for Finnish citizenship (certificates in Finnish and Swedish)
  • demonstrating your language skills for an employer
