The biggest problem facing schools having social justice curricula, beyond implementation of a programme, I claim, is the problem of "justification": what grounds what in social justice and how do we make this manifest to ourselves and to the curricula? If we cannot address this, then social justice curricula are doomed to begging the question. I claim that a ranking of human rights is not only necessary to adjudicate competing claims for social justice and at the same time, thwart interference with already agreed-upon human rights: it is necessary for "any" curriculum of social justice for schools. That is to say, curricular programs of social justice "cannot" justify social practices that interfere with human rights, nor can they teach otherwise than this. Due attention to the violation of human rights is necessary, I shall argue, and must be central in the discussion of education for social justice.
