This chapter analyzes if Swedish principals embrace a number of public core values differently depending on whether they are working for public or private schools. 371 principals (202 working for public schools and 148 for private schools) have completed a written questionnaire containing 15 postulations connected to five core values: political control, rule of law, economic efficiency, professionalism and users’ influence. The study’s main finding is that the differences between the two categories of principals are quite small. Discernible differences are expected, e.g. that principals in independent schools are a bit more prone than principals in public schools to letting pupils and parents influence school activities, and that principals in public schools seem a bit more inclined to interact and listen to politicians than principals in independent schools. The result implies that factors other than the type of organization – private or public – are more important for the way principals relate to public core values. For example, the comprehensive and detailed regulation of the Swedish educational system, or professional norms among principals, might explain the high degree of conformity.
