Female students in mechanical engineering have better chances to achieve an academic career than women in other academic disciplines. In this article we reconstruct how female mechanical engineers interpret for themselves their success. Our reconstruction of the self-interpretations focusses on the "internal biographical mechanisms of regulation" (GIEGEL, 1988). The empirical material encompasses three qualitative primary data collections with female professors, female doctoral candidates, and female students of mechanical engineering. The methods used are narrative and problem-centered interviews. These primary data collections are then analyzed by applying the method of thematic coding. The analysis shows an extraordinarily high level of accordance between the three groups. The first accordance relates to family up-bringing, which was aimed at enabling the children to make individual decisions Further agree-ments concern: 1. biographical resources: a high level of self-confidence of being successful by realizing their own objectives; 2. the dominant interest in technology, based in the natural sciences; 3. the relation to the performance principle: the female mechanical engineers embrace great determination for perfor-mance as an essential basis for realizing one's own interests. These three dimensions specify their "internal biographical mechanism of regulation". It can be assumed that women who opt for mechanical engineering very often possess a distinct aspiration for success. Pre-sumably they would be successful in most other disciplines.
