This article reviews the impact of discourses on "New Public Management" (NPM) on compulsory schooling in Switzerland during the last two decades and traces its implementation in the Canton of Bern. The analysis suggests that while NPM reformers initially promoted increased school autonomy, the introduction of market elements and school choice, the focus subsequently shifted to a concern with school management, supervision and accountability. NPM-guided reforms led to the introduction of headteachers and quality management procedures in a majority of cantons. Ethnographic research in the Canton of Bern shows that NPM-influenced decentralisation policy results in a growing standardisation of schools' conditions and processes. Additionally, lay school boards as traditional, democratically legitimised bodies of local supervision are coming under threat.
