Today, the concepts of “epistemological belief” (EB) and “locus of control” (LOC) have become important in education. It is considerable to investigate these concepts on teacher candidates who are the teachers of the future. This study aimed to examine the LOC and EB of social studies teacher candidates. The research, which adopted a survey model, was conducted with five hundred and fifty social studies teacher candidates studying at seven state universities in Turkey. The Locus of Control Scale and the Epistemological Belief Scale were used to collect research data. Descriptive statistics, independent samples t-test, one-way analysis of variance (ANOVA), the Scheffe test, and correlation analysis were employed in the data analysis process. When evaluating the research results, it was determined that female teacher candidates have a higher external LOC. No significant difference was observed in social studies teacher candidates’ LOC regarding their parents’ educational grade level. It was observed that there was a significant difference in the EB of social studies teacher candidates regarding gender. It was revealed that female teacher candidates had underdeveloped/immature EB. No significant difference was found in the EB of social studies teacher candidates based on their parents’ educational levels or grade. It was observed that there is a weak but positive significant relationship between the social studies teacher candidates’ LOC and EB and their sub-scales.
