This study aims to determine the level of unethical behaviours (UBs) of students studying in the field of sports sciences. In this research, the explanatory sequential design was used for mixed research approaches where quantitative and qualitative data collection tools were used. The quantitative part of the study attended 465 Sports Science Faculty students in Kirikkale University during the fall semester of 2017-2018 academic year. Following the quantitative research qualitative data were obtained with five scenarios prepared by the researchers. As a result of the research, it was seen that UBs differ according to gender, class level, and the department of education. In the scenarios presented in the qualitative section of the research, it was determined that students who have higher Unethical Behaviours Climate Scale (UBCS) scores tend to apply more sanctions to the students when they are teachers. It has been observed that male students are more likely to have UBs than women. Not using technological tools in the lessons was defined as UB. The results of the study showed that the source of student UBs could be the teachers or the students themselves.
