This study aims to examine a theoretical model of the role of conscientiousness and achievement motivation on career self-efficacy with mastery goal orientation as a mediator fitted with empirical data. The variables in this study are conscientiousness and achievement motivation, mastery goal orientation and career self-efficacy. Respondents in this study were 350 mature student (studying while working) of MercuBuanaMeruya university Jakarta. A scale of conscientiousness was based on the paper of Costa and McCrae (Pervin and John, 2001), a scale of achievement motivation by Pintrich (2008), a goal orientation mastery scale from Elliot and Pintrich (2000) and a self-efficacy scale based on Betz and Luzzo, (1996). The entire scale used in this study was adopted and modified by the author with a Likert scale model. Data analysis techniques to test the theoretical model in this study used a Structural Equation Model (SEM) through a Linear Structural Model (LISREL), software version 8.7 The model test results show that the hypothetical model has a fit index RMSEA = 0.066, NFI = 0.99 NNFI = 0.99 CFI = 0.100. IFI = 0.100 means that the hypothetical model or hypothesis can be accepted or fitted with field data. It means that "the role of conscientiousness and achievement motivation towards career self-efficacy with goal orientation mastery as mediators as been fitted with data". The results show that the theoretical model that describes the role of conscientiousness personality and achievement motivation towards career self-efficacy with mastery goal orientation as a mediator fitted with empirical data.
