The purpose of this study is to clarify the problems of the school police officer system and to suggest the improvement plan. School police officers have emerged as one of the measures to prevent school violence. At present, one school police officer is responsible for 10.5 schools on average. In addition to school violence prevention education, they are also responsible for participating in school violence councils, dismantling violent circles, counseling and communicating with students, counseling and accepting school violence reports. Some of them are police officers in charge of juvenile police schools. However, some of the inconveniences reported in the press have raised the question of the existence of a school police officer system. In this paper, I clarify that there are limitations in the implementation of crisis-related student-related tasks, role confusion due to performance-based evaluation, lack of manpower, and overwork in relation to the work of school-dedicated police officers. In addition, the division by the school characteristics, the role regulation, and the construction of the circulation and reproduction system are required to be faithful to the police s original work.
