This research aims at exposing the influence of career choice factors from Career-Choice-Model of the Social-Cognitive-Career-Theory (Lent, Brown & Hackett, 1994, 2000, 2002) as well as the previously formulated Social-Cognitive-Theory by Bandura (1986). The first sample in January 2011 (650 students), collecting supportive and inhibiting context criteria as well as self-efficacy, uncertainty and activities of career choice. It was assumed that parents, friends, career counselling and also barriers have an influence on the actual career choice, hence, a confirmatory factor analysis with a follow-up analysis of covariance was performed to reassess the amount of influence. Further, differences between males and females were explored using multiple group-comparisons. The resulting structural coefficients arm three assumptions: Firstly, the direct influence of parents' and friends' support on self-ecacy. Secondly, the direct influence of parents' and friends' support as well as barriers' inhibition on uncertainty of career choice. Thirdly, it could be proven that support in the subject career counselling also has an impact regarding uncertainty of career choice while being mediated by self-ecacy. The second sample in May and June 2011 collected distal context criteria in addition to learning experience, outcome expectation, uncertainty and activities of career choice (480 students). Again the research instrument used was a questionnaire, and the average age of the students (median) was 15. According to presumptions made by the Social-Cognitive-Career-Theory, resulting structural coefficients attest to both distal context factor, parent-child relationship and support for school, direct influence on learning experience only. Further, both samples suggest great impact of sex. High effect sizes calculated via multiple correlated coefficients confirm the influence of proximal context criteria, as assumed by Bandura and Lent, Brown & Hackett.
