Portfolios are used in teacher education programs to provide evidence of pre-service teachers' professional growth and development. As programs are better able to integrate technology into the teacher preparation curriculum, many educational institutions are implementing electronic versions of portfolios (e-portfolios) on a widespread basis. Uses and types of electronic portfolios continue to grow and evolve, building on the visionary work of Helen Barrett (1999). Many of these efforts have moved beyond the pilot phase, with some high stakes, such as institutional accreditation, riding on the outcome of the implementation. This article describes the process of implementing e-portfolios in colleges of education at three different universities across the United States (Arizona State University, West Campus; Drake University in Des Moines, Iowa; and the University of Tennessee at Knoxville). In each case, the college is a recent adopter of e-portfolios, with findings described from the first three years of implementation. (Contains 8 figures and 3 online resources.)
