Human judgements underlie all assessments regarding the quality of students' understandings, and such judgements are conceptually complex and elusive. The study of the complexity of the judgement process is in its infancy but clearly warrants further critical investigation. However, what is demonstrated from the wide variety of international teacher judgement practices presented in this volume is that teacher judgement requires a lot more than a set of standards, criteria and annotated examples. Understandings of assessment theory by pre-service teachers through to more experienced teachers, and opportunities for all to critically reflect and consider their judgements of student work, are vital. Teachers are struggling to maintain their interpretive freedom at the local, professional level in contexts where central policies promote standardisation or 'regulation' of judgement practice, for accountability purposes.
