“…Sorensen and Dumay (2024) show how the EU Treaty’s distribution of competences continue to shape the roles and interaction of field actors, including the opportunities and limitations for the European Commission in aligning and creating interaction between policy instruments. In combination, the papers suggest the centrality and breadth of the Commission’s activities, from orchestrating the European Semester (Eeva, 2021) and the ET 2020 Workings Groups (Gain, 2023), to its convening power and funding provision in European quality assurance (Grek and Russell, 2023), and as a boundary organisation maintaining and (re-)ordering boundaries towards other fields in the EU’s governance of teachers (Sorensen and Dumay, 2024). The papers thus show how the European Commission as a ‘purposeful opportunist’ (Cram, 1993: 141) has managed over time to create new policy arenas and stimulate demands for EU level action by its agenda-setting, funding incentives and stakeholder mobilisation (Harmsen, 2015).…”
