Open UAS students are required to have university level study skills. Students themselves are responsible to have these skills. The skills include among other things writing an essay answer. Usually a secondary level education (high school, vocational school) gives a good base for university level studies.
Usually a good base for Master's level studies in Open UAS consist of a Bachelor's degree and three years work experience (courses marked "Master" in the supply lists).
Open UAS students are required to have sufficient language skills. UAS students are required to have C1 level language skills in terms of the teaching language (either Finnish or English). Some English degrees also require B1 level Finnish language skills, even though teaching is in English. This is mentioned in connection to the degree's Open UAS offering.
