The aim of this study is to adapt the Generalized Expectancy for Success Scale, which was developed by Fibel and Hale (1978) and revised by Hale et al. (1992) into Turkish in terms of adaptation, reliability and adaptation. This study modelled by survey is a scale adaptation study. The scale was adapted into Turkish culture in terms of language equivalence, reliability and validity. The population of the study consisted of the students of the Kazim Karabekir Faculty of Education, Faculty of Literature, Faculty of Science and Faculty of Theology of Atatürk University. All students in the Faculty of Education, the Faculty of Literature, the Faculty of Science and the Faculty of Theology and the 4th grade students who are subject to the pedagogical formation program were tried to be reached and as a result, the research was conducted with 1450 students. The results have shown that the scale had language validity and translation period was implemented successfully. According to exploratory factor analysis's results, the structure was consisted of three factors--21 items, which explained 46, 6% of variance. According to study results, it is determined that the adapted version of the scale is used as a reliable and valid instrument to assess the generalized expectancy for success of Turkish university students. The scale is also used to determine sub-dimensions e.g. individual expectancy, social interaction and failure as well as the generalized expectancy for success.
