Soft skills are factors that support students success in learning mathematics. The importance of the students soft skills, unfortunately, are not in line with at the students abilities in these competence. Therefore, we have to implemented a learning model that is expected to lead development soft skills of the students in mathematics. Generative learning model is applied in this study as an alternative learning is predicted to stimulate development soft skills of the students. This study is aimed at determining the contribution of generative learning model of the enhancement of soft skills for difference school levels (high, medium, low).This study is quasi-experimental research involving 191 students of eight-grade senior high schools in Yogyakarta involving three levels of school. Research hyphothesis was examined at 5% level of significance, data analyzed using t-test, and twoway ANOVA. The results of the study are: (1) there are different achievement, the enhancement of soft skills of student between experiment of class and control class; (2) there is no interaction betwee learning and school level toward the enhancemen soft skills.
