One of the largest on our fields

Diak is Finland’s largest provider of UAS-level education in social work. In the health and social care sector, it is the only national UAS offering education and services for workplace organisations across Finland.

We offer degree programmes in nursing in three languages: Finnish, Swedish and English.

Diak is responsible for over 90% of the provision of UAS-level education that qualifies graduates for diaconal and youth work roles in the Evangelical-Lutheran Church of Finland. Approximately one in four of Diak graduates complete a diaconal degree.

Diak is the only Finnish UAS that offers education in public service interpreting.

Through its RDI activities, Diak participates in the regional, national and international development of its educational fields.
