Social justice is a key concept in current education policy and practice. It is, however, a problematic one in its application to schooling. This paper begins with a critique of the account of social justice offered by Gewirtz followed by an alternative philosophical notion based on the perfect world argument and the just society where equality is to the fore. This leads on to an exploration of what it is to be an educated citizen, consideration of the just school and (...) discussion of the place of the school as an instrument for attaining social justice. The conclusion draws attention to the importance of the policy web as a way of developing coherent and unified policy designed to achieve social justice for all. (shrink)
