All our assessments are based on reliable and scientifically founded methods, which we continually monitor and nuance. In line with our holistic approach we apply the following model: At the level of behavior we evaluate the specific performance of the candidates, i.e. their skills and competences on the one hand, and their needs and motives on the other hand. Furthermore, also their performance potentials are taken into consideration. In their totality the evaluations allow conclusions regarding the former, present, and future performance and performance potentials of the candidates.
