NCREST, through Teachers College, was a member of the National Partnership for Excellence and Accountability in Teaching (NPEAT), a national coalition of universities, professional associations, research and development institutes, and other education related organizations. The Partnership’s work over five years, funded by the US Department of Education, was an examination of teacher preparation and professional development; the nature and consequences of partnerships in collaborative research and development; the use of standards and assessment in teaching and teacher education; and the role of educational technology in teacher education. NCREST engaged in research and development work focused on experienced teachers’ opportunities to continue to grow professionally as a consequence of their membership in nontraditional educational contexts (Professional Development Schools, charter and restructuring schools, teacher networks, and mentoring and induction programs). The National Commission on Teaching and America’s Future (NCTAF) is leading the NPEAT strand devoted to the study of standards and assessment. In addition, the NCTAF-led standards and assessment work will be done in collaboration with a number of organizations, including the National Board for Professional Teaching Standards, the National Council for the Accreditation of Teacher Education, and the American Association of Colleges for Teacher Education.
