The extent to which the goals and contents of (compulsory) education should to be regulated has been a complicated balancing act in the Netherlands. Against a background of a longstanding statutory tradition of freedom of education, governmental decisions about ‘what knowledge is of most worth’ have been delicate. The purpose of the analysis described in this article is to disentangle, interpret and discuss this complicated balancing act between curriculum regulation and curriculum freedom during the past 40 years and to learn from other countries by putting the results into a wider European curriculum policy perspective. The contribution will end with discussing issues that need to be carefully considered with respect to the recent Dutch policy shift towards output regulation by means of mandatory achievement tests for mathematics, mother tongue and English at the end of lower secondary education.
