This report on the inservice education and training (INSET) of teachers in England and Wales has two purposes: (1) it describes and critically analyzes five major, significant, and potentially adaptable innovative INSET practices; and (2) it relates these five case studies to the national INSET context and explores some of their implications for the future of INSET nationally and internationally. Section One talks about the development of INSET, previous programs leading up to its establishment, present functioning and objectives, and outlines the contextual framework for INSET innovations. Five case studies of innovative approaches to INSET in England and Wales are presented in Section Two. They include: Teacher Induction Pilot Schemes Project; Colleges of Higher Education and INSET; INSET at a Distance; the Open University; Local Curriculum Development and INSET; and School-Focused INSET. The final section identifies some of the major issues arising from the first two sections and explores their implications for INSET policy in England, Wales, and elsewhere. A bibliography is included. (SK)
