National Certificates of Language Proficiency (YKI)


National Certificates of Language Proficiency (YKI) are language tests for adults. They test your standard language skills in practical situations. You can officially prove your language skills in different languages with a National Certificate of Language Proficiency.

The National Certificates of Language Proficiency (YKI) are the language test system of the Finnish government. You can use these certificates when you

  • apply for a job or study place
  • apply for Finnish citizenship (certificates of Finnish and Swedish skills)
  • must prove your level of language skills to an employer.

All National Certificate of Language Proficiency tests consist of four parts: speaking, listening comprehension, writing and reading comprehension. You will get a separate grade for each part.

You can take the test in the following languages: English, Finnish, French, German, Italian, Northern Sámi, Russian, Spanish and Swedish.
