[Excerpt from publisher] The report Teachers Matter: Attracting, Developing and Retaining Effective Teachers is about school teachers - their preparation, recruitment, work and careers. Its specific concern is policies that contribute to attracting, developing and retaining effective teachers in schools. The report draws on the results of a major OECD study of teacher policy conducted over the 2002-04 period in collaboration with 25 countries around the world (see Box 1). The fact that so many countries took part indicates that teacher issues are a priority for public policy, and likely to become even more so in future years. The report aims to provide a comprehensive international analysis of:Trends and developments in the teacher workforce.Evidence on the key factors in attracting, developing and retaining effective teachers.Innovative and successful teacher policies and practices.Teacher policy options for countries to consider.Priorities for future work at national and international levels.
