This article analyses how education is positioned in the current concerns about security and extremism. Initially, a central dilemma is acknowledged: that schooling appears to be simultaneously irrelevant to the huge global questions of security and yet central to the learning of alternative ways to conduct human relations. With regard to extremism, two aspects of importance in ideological compliance or challenge are firstly the attempted securitization of education, and secondly the role of education in young people joining or supporting extremist movements. Educational approaches within transitional justice underline the importance of tackling violence in schools and promoting a human rights culture that promotes both human security and ultimately national security.
