De mediator als professional of de professional als mediator?

The mediator as a professional or the professional as a mediator? In this contribution the focus is on whether mediation, as it is practiced today, can be regarded as a profession and if so, whether it belongs to the ‘new’ or ‘old’ professions. In an attempt to answer this question the structure of the body of knowledge and the predictability of the outcomes of the application of that body of knowledge are discussed.
