This paper describes theoretical, political, and practical contexts for developing standards of practice for teaching, creating a framework for career-long professional learning and establishing a set of ethical standards for the profession. It positions the work of the Ontario College of Teachers within the broader context of Ontario education and the political milieu. The College was recently founded to license, govern, and regulate the practice of teaching. The paper begins by providing background information on the College, then it focuses on the mandate of the Standards of Practice and Education Committee and staff in the Standards of Practice and Education Unit of the College. After discussing the political context, the paper describes the task of developing standards of practice for the profession, explains self-regulation and standards of practice, and looks at the College's work in the Ontario context. It describes the beginning of a conversation with the education community and the public about standards and looks at focus groups designed to address the issue of standards and professionalism. Finally, the paper discusses the rest of the development process (other data sources, the process of writing the document, feedback sessions, and the future). (Contains 10 references.) (SM)
