Over the past 25 years the field of sport psychology has developed very successfully in the Netherlands. Until about 1985, sport psychology played a rather marginal role. Since then, however, a remarkable improvement can be observed. Currently, a considerable amount of attention is payed to the structural integration of sport psychology into research and education programs of several universities. Attitudes toward sport psychology and mental training on the whole are very positive. Further, the media and the sports world treat sport psychology with an attitude that is more benevolent than ever. An accreditation system was introduced approximately 3 years ago, which will ensure a baseline level of quality in sportpsychology programs. The establishment of a training program for applied sport psychologists in 2007 is a direct consequence of this accreditation system and stresses the progressive professionalization of the field of sport psychology in the Netherlands. © Hogrefe Verlag.
