The aim of this study is to determine the relationship between the individual values and critical thinking skills of prospective social sciences teachers. The sample of the research is composed of a total of 298 prospective teachers, who are first-year, second-year, third-year and fourth-year students. These prospective teachers were randomly selected using the stratified sampling method which is one of the random sampling methods via the maximum variation sampling method in purposive sampling. The data of the study have been obtained using a Personal Values Scale and Critical Thinking Scale. In view of the research findings, a positive significant result has been obtained among the scores for the critical thinking and personal values factor perceived by the prospective teachers. Moreover, it has been observed that personal values factors collectively predict 42% of the critical thinking score. (Contains 4 tables.)
