If you want to prove your language skills for the Finnish citizenship application with YKI certificate, you must participate in the intermediate level YKI test in Finnish or Swedish language.
All YKI tests consist of four subtests: speaking, listening comprehension, writing, and reading comprehension. You will get a separate grade, i.e. a proficiency level assessment, for each subtest.
For the Finnish citizenship application, you need at last grade 3 in two subtests. However, note that only the following subtest combinations are accepted:
1) speaking and writing
or
2) listening comprehension and writing
or
3) reading comprehension and speaking.
Participating in the YKI test
It is important that you participate in all four subtests. Otherwise, you will not be given a YKI-certificate at all. You must complete the entire examination on the same test day.
However, you may combine two separate YKI certificates that together form the accepted subtest combination 1, 2, or 3.
If you want, you can also take the advanced level YKI test.
