The present essay problematizes the centrality of scale in educational policies, particularly in curriculum policies. To empirically consolidate the place of scale in education, we will analyze the "Glossary of Curriculum Terminology" (UNESCO/International Bureau of Education), in this article freely translated as "Glossary of Curriculum Terminology" (2016). The hypothesis of this text resides in the curriculum as a policy of scale. To this end, we articulate the debate of curriculum theory (LOPES, 2015, MACEDO, 2012, 2019) with political theory (MOUFFE, 2011) and the epistemology of scale, developed by Moore (2008). Our intention is to question the role of scale in educational policies, given that it is not a mere adjective of the level of governance of curricular actions, but an operation of antagonisms in the relationship between institutions and curricula.
