Despite the growing body of literature and general interest in the intersection between the capabilities approach (CA) and education, little work has been done so far to theorize democratic education from a CA perspective. This essay attempts to do so by, first, getting clear about the theory of democracy that has emerged from Amartya Sen's recent work and understanding how it informs his CA; and, second, by carefully drawing out the implications of these aspects of Sen's thinking for democratic education. Ultimately, I argue that Senian democratic education (SDE) is a composite of various learning processes that enhance one's capability for social and political (democratic) participation. Particular attention is given to the learning that happens through one's actual engagement in democratic practices and that which happens through one's formal schooling. I call the former of these learning processes SDEp and the latter SDEs. SDEp is democratic life itself, and its effectiveness both depends on and contributes to the development of a culture of political participation within society. SDEs is best understood as the process of facilitating children's achievement of democratic functioning, that is, children's achievement of certain "beings and doings" associated with the emergence and exercise of their individual and collective democratic existence.
