Ideas about what makes a good teacher are important in thinking about educational reform, and have come into focus recently. These ideas are contested and open to change. The first part of this paper traces models of the good teacher in Australia from the colonial-era good servant, through an ideal of the autonomous scholar-teacher, to contemporary lists of teacher competencies. The second part looks more closely at the incoherent but insistent way the good teacher is now defined under neoliberal governance by teacher registration authorities. The third part of the paper makes proposals for a new understanding of good teachers: based on understanding the labour process and occupational dynamics of teaching, the intellectual structure of Education studies, and the overall logic of education itself.
