In this paper, we describe assessment in seminars where high student activity is encouraged. The aim of our work has been to design assessment events that result in deep learning and high student activity, but still provide the teacher with a reliable basis for justice in examinations. We will discuss a course in electronic commerce where we have been working with two progressive seminars. Experiences from this attempt are discussed and analysed in the paper.
