 Gray, a teacher educator and former high school English teacher, was motivated to create a different form of professional development for teachers, one that made central the knowledge, leadership, and best practices of effective teachers, and that promoted the sharing of that knowledge with other teachers.In partnership with Bay Area school districts, BAWP created a range of professional development services for teachers and schools interested in improving the teaching of writing and the use of writing as a learning tool across the curriculum.The structure of this first writing project site's programs formed the basis of NWP's "teachers-teaching-teachers" model of professional development.
