This research aims to conceptualise and reflect on DEEEP's understanding of Globalcitizenship Education(i.e., GE) in a way that is practice-led and rooted in practitioners’ experiences. We argue that the strategies practitioners use to negotiate the institutional and conceptual challenges of GE should be more systematically engaged with and central to our understanding of GE, and provide critical lessons for how practitioners can be supported, but also how we can understand the GE that results.
