The aim of this study is to determine the risk level of high school students for dropout. The sample of the research in the descriptive survey model consisted of 578 students studying in public high schools in the central districts of Mersin. The "School Dropout Risk Scale" was used as a data collection tool in the study. According to the findings obtained as a result of the research, male students are more likely to drop out of school and behave antisocial than female students. It has been observed that there are silent types who have a perception of failure, do not show that they will drop out of school, are in the risk group, and that the students expressed a "low" level of opinion regarding the total score at the risk of dropping out of school. In line with these findings, suggestions were made to prevent school dropout.
