The transcript of records and the certification of student status that can be ordered through WebOodi are now digitally signed. They are as official as the traditional paper versions, signed and stamped, but only when used in their original pdf format. This means that you should not print them, or alter or edit the files in any way.
You can find the function in WebOodi in Tools – Transcripts and certifications of student status. Both documents are available in Finnish and in English.
