Several authors have underlined that processes of Europeanisation of education emerge despite the European Union's lack of formal power in this area. This article argues on the contrary that its lack of power precisely enables the EU to open up a range of possibilities for its involvement in this sector, among which the ET2020 Working Groups (WG) of the Open Method of Coordination (OMC). Based on observations of WG meetings and interviews with key actors, and using Niklas Luhmann's systems-theory, we aim to show how the distance separating the ET2020 WG from the formal circuits of European decision-making acts as a resource for the development of a European discourse on education. Alongside the ordinary legislative procedure based on voting and implementing collectively binding decisions, the alternative political circuit of the OMC is based on the irritation of a set of education sector stakeholders through the creation and dissemination of reports of 'good practices'. In doing so, the ET2020 Working Groups illustrate how politics transforms itself and redefines its boundaries when it is structured at the European level rather than at the level of the nation-state.
