The aim of this study is to review the relationship between the time management skills and cyberloafing behavior of school managers. Descriptive survey and relational research models were used in this research. Data was collected from 181 school managers at official elementary schools, secondary schools, and secondary education schools in the district of Nizip in Gaziantep during the 2017-2018 school year. A "Time Management Scale", which looks at time planning, the effective use of time and the dimensions of time traps together with a "Cyberloafing Scale" which is composed of both significant and insignificant cyberloafing dimensions were used as data collection tools in the research. The collected data was analyzed using descriptive statistics and correlation analysis. The research concluded that the better the school managers were at time planning and using their time effectively, the less prone they were of falling into time traps. In other words, the better their time planning and effective use of time, the more their significant and insignificant cyberloafing behavior decreased. As a result of the regression analysis, it was seen that only time traps, among the subdimensions of time management, significantly predicted cyberloafing behavior.
