The National Writing Project designed the Professional Writing Retreats to support writing by teacher-leaders for audiences of scholars, practitioners, policymakers, and other members of the public who have an interest in education. These writing retreats focus on writing about the profession of teaching, giving teachers a chance to write about their practice, make claims about policy, enter into discussions about school reform, argue about ideas concerning literacy and learning, and address a variety of other concerns about teaching writing. The authors believe that professional writing by NWP teacher-consultants and directors can achieve the following ends: (1) By writing about school reform, NWP colleagues can help resituate reform efforts by giving voice to the most powerful agents of change in schools: teachers; (2) By writing about practice, teachers can make public the vast resources of their knowledge, making it available to other teachers, administrators, and even legislators and parents; and (3) By writing about professional concerns, they enter into the scholarly discussions about teaching writing, making NWP's knowledge more visible to the community of researchers. This "Handbook" offers advice about planning, funding, and conducting a retreat and provides tools and resources to help sites design local retreats. Appendices include: (1) Pre-retreat Readings; (2) Pre-retreat Materials; (3) On-Site Retreat Materials; and (4) Retreat Anthology Materials.
