Globalising processes are shifting the established nation-building project of twentieth-century national education systems. This historic axis between education and territorialised state power is being re-spatialised and remade as a globally networked, lifelong learning educational order. Political sociology of education theorises these de- and re-territorialising trajectories; yet the practical processes of remaking educational spaces are less well documented. The concept of "boundary work" provides a lens for understanding the interplay between political and sociological processes that remake educational spaces over time and scale. Analysing two visions of education at the start of the twentieth and twenty-first centuries, I track the shifting configuration of actors and processes involved in boundary work. I argue that educational spaces are "things of boundaries" and lifelong learning reforms indicate processes of boundary work involving emergent educational actors: "professionals-who-educate".
