The aim of this study is to develop a measurement tool for school administrators to use crisis management skills in terms of school development as pre-crisis (PC), crisis moment (CM) and post-crisis (PC). In the study, the steps of the process carried out for this purpose are explained. In the scale development process, firstly, scanning of the literature was carried out and similar scales were examined. Expert opinion has been consulted for the validity of the scale. The study group of the survey has 216 vocational high school teachers working in North Cyprus in the 2016-2017 school year. Factor analysis was performed to determine the validity of the scale. The results of the factor analysis revealed that the scale factor was a factor and that the total factor variance was 50,211% for one factor. The reliability coefficient of the scale (Cronbach alpha) was found to be 0.95. The value of Kaiser-Meyer Olkin (KMO) was found to be 0.917. Therefore, this scale has led to the conclusion that school administrators can accurately and credibly measure crisis management skills in terms of school development.
