The Teachers College Reading and Writing Project is a staff development organization that works in intimate and long-lasting ways with communities of educators in the New York City metropolitan area and also provides more limited assistance to educators in schools from all over the United States. Currently the Project serves over 100 schools. For two decades, the Project has supported educators establishing reading and writing workshops in which teachers act as mentors and coaches to children. Project staff and teachers become co-researchers, observing what children do in writing and reading, theorizing about what their behaviors mean, and planning teaching moves to help them learn. To nurture this school-based work, Project staff meet at the College with educators from Project-schools: Each week over 100 teachers gather in study groups focusing on becoming teacher-leaders in workshop teaching, and each month over 100 principals gather focusing on the problems, challenges, and opportunities of being a school leader in literacy education. The Project's school-based consulting, study groups, and think-tanks are complemented by an array of other professional education opportunities at the College. Throughout the year, thousands of teachers attend sixty full-day Project-run conferences providing information and insight about how to structure and sustain high quality literacy education. Every summer, three thousand teachers attend one of several week-long Project Institutes which include keynote addresses, small groups study, and interactive discussion groups. The Project was founded and is directed by Lucy McCormick Calkins, Professor of Education.
