This study tries to explore the relationship between prospective EFL teachers' locus of control and academic self-efficacy in Turkey. For the purpose of the study, the quantitative data of the research was collected through Multidimensional Locus of Control Scale developed by Levenson (1974) and adapted to Turkish by Kiral (2012). The scale, consisting of 24 items (6 point Likert type), simply examines the internal and the external locus of control of pre-service EFL teacher candidates. It measures (a) internal locus of control (8 items), (b) locus of control based on others (6 items), and (c) locus of control based on chance (5 items). The Cronbach Alpha coefficient for this scale is 0.77. As to the Academic Self-efficacy Scale, College Academic Self-Efficacy Scale was adapted from Owen & Froman (1988), consisting of 33 items measuring male and female ELT students' academic self-efficacy beliefs as a whole. The Cronbach Alpha coefficient for this scale is 0.83. The scale is a 5- point Likert scale ranging from 'very little' (1) 'quite a lot' (5). It is assumed that the higher the locus of control of EFL teachers, the higher level of academic self-efficacy is. At the end of the study, considering the results, some recommendations will be made for language instructors at these institutions.
