Despite being a small country, Finland has been highly visible in international Computing Education Research (CER). This is demonstrated by the presence of several important research groups, dozens of graduated PhD students in CER during the last 20 years, and the success of the Koli Calling International Conference of CER, which has been running for 20 years now. In this chapter, we present the development of the CER field in Finland, the profiles of various research groups, and the roles of several national level networking activities which have supported the field. We discuss factors behind the strong presence and success of CER in Finnish universities.
