This is an edited version of a presentation Michael Fielding was invited to give in April 2006 at the Post Primary Teachers' Association Professional Conference. The conference, entitled Quality Teaching--Leading the Way, took place at the Wellington Convention Centre, Wellington, New Zealand. In his presentation, Michael contrasts two approaches to consideration of the idea of 'quality' in relation to teaching: performance quality and educational quality. The former is a disciplinary device designed to control at a distance. The latter requires rigorous reflexive thinking from which emerges judgement of values. The ways in which both approaches, and their implications, continue to resonate are examined.
