Education has always been an integral part of Finnish national programs aiming at culturaldevelopment. Finnish students have been very successful in the different tests of the internationalcomparative PISA study(The OECD Programme for International Student Assessment)(Valijarvi et al. 2007). In Finnish culture，the profession of teacher has been seen as one of themost important professions of society. Teachers have also been trusted to do their best as trueprofessionals of education. A high degree of school and teacher autonomy in decision-makingmay thus be assumed to have been one major factor contributing to Finlands high performancein PISA.
