The Center for the Study of Teaching and Policy at the University of Washington draws on the scholarly work of four different universities, including Stanford, the University of Michigan, and the University of Pennsylvania. The purpose of their research is "to identify ways that leaders, policymakers, teacher developers, and the reform community can support teachers' work and careers." Researchers will want to look at the ongoing research projects in progress at the Center, which include examinations of the role of unions in the teaching environment and a comparative study on school district investment in the improvement of teaching. Probably the most valuable aspects of the site are the online policy briefs, occasional papers published by the center, and working papers from the past several years. Lastly, visitors have an opportunity to sign up to receive updates on the Center's work via email.
