Since 1997, the Amsterdam Faculty of Education (EFA) has been officially recognized as a center for experimental teacher education. This paper describes the development of an assessment system and a World Wide Web-based portfolio system to help students take responsibility for their learning and their competence at three consecutive integrative assessments. The introduction provides background on the EFA and summarizes three ideas that provide the basis for the program: students need to be capable of managing change; students need to be given responsibility; and students have a considerable degree of freedom in filling out the details for their own learning processes. The central concept of meaningful learning is discussed in the second section, including authentic learning in professional education and the phases of the learning process (i.e., orientation, planning, execution, and evaluation). The third section describes program facilities in relation to these learning processes. The following program facilities are presented in detail in the fourth section: (1) orientation (the role of competency descriptions and moments of integrative assessment); (2) planning (the role of contracts); (3) execution (learning practices and the role of resources and metawork); and (4) evaluation (the role of the portfolio).
