This article explores empirical and theoretical literature relevant to accreditation of teacher education programs. The lack of substantial research on accreditation makes it impossible to make empirically based claims about the value-added of such processes, including how accreditation processes enhance the professionalization of teacher education. Contemporary scholarship, especially in sociology, also raises questions, especially about the uncritical acceptance of the professionalization movement in teacher education. After briefly reviewing three lines of criticism concerning professionalization, the authors use that literature to "read" both Wise's (2005) description of the benefits of NCATE's work and Murray's (2005) description of TEAC's role in enhancing professionalism in teacher education. Both authors presume that professionalization is a good; both fail to confront some of the central concerns about the exclusionary practices of professions in their descriptions of NCATE and TEAC. The authors conclude by suggesting that the professionalism movement within teacher education --while important--requires that we encourage and embrace both internal and external forms of criticism.
