Teacher organisations are an integral part of the education system. Their evolution is important to the development of education and the teaching profession. The organisation of public school teachers impacts on public elections, education policy, and school organisation. Conversely, a nation's history, institutions, and policy shape the strategies available to organised teachers. Governments internationally initiated change in curriculum, education governance, accountability measures, and teacher unionism that impacts on teacher professionalism. Understanding the influence of government and teacher organisations relations on the process and the nature of change in education can assist the parties to appreciate the importance of their respective roles in education reform. The present comparative study is an explanation of three types of organised teachers and state relations with reference to change in education as exemplified in Quebec and Saskatchewan, Canada, and Victoria, Australia.
