The present study examines the relationship between Locus of control and translation achievement. The participants included 100 (73 female and 27 male) BA senior students studying English translation as their major at Imam Reza International University and Khayyam Institute of higher education. Both male and female students responded to Internal Locus of Control Index (ICI) questionnaire. They were divided into Internalizers/ Externalizers according to the scores gained in the ICI. The results of the study indicated that students’ Locus of control have a positive and significant relationship with their translation achievement. Internalizers outperformed Externalizers in their translation task and it also revealed that as translation students’ LOC increases, their translation achievement increases significantly. Locus of control as a psychological construct, has been the focus of attention in recent decades, therefore, the findings of current study will result in higher translation achievement of students and will help translation instructors plan better for the improvement of their students.
