This was studied on the amend of the School Violence Prevention and Countermeasure Act(the rest is as SVPC Act) and the before reviews, so wanted to derive a legal improvement direction. SVPC Act was enacted in 2004 and the latest amendment in 2019. Before the revision in 2019, there was no separate retrial procedure and followed on the appeal procedure under the Elementary and Secondary Education Act. After he amendment in 2019, the retrial structure was unified into administrative adjudication and administrative litigation. And the self-governing committee established for each school was established within the regional office of education. It strengthened professionalism and allowed fair judgment to proceed. The revision was made in the direction of slightly lowering the parent participation rate and increasing the proportion of experts. Before the 2019 revision, the role of the school president was given to the executive body, but introduced a self-solving system in which the decision-making authority is shared with the head of the school. This has been strengthened better in the educational procedural aspect. A system of deferment of writing in student records has been established, so the function of education and guidance for the perpetrator student was strengthened. Nevertheless, there are still tasks for improvement, such as setting standards for judging school violence-related behaviors, difficulties in taking written apologies, strengthening professionalism in institutions, and educational measures for students of victim and perpetrator. Prevention and resolution of school violence disputes should be able to harmoniously reflect and adjust conflicting interests. Various positions of the perpetrators and their parents, the victim students and their parents, the friends of the students involved, and the school’s homeroom teachers, counselors, school organizations, relevant departments of the local education office, the school violence review committee, and police activities in schools, etc. Human rights education and local social welfare systems should be combined from a preventive point of view in these procedures. Above all, the school violence dispute resolution system needs to be designed and restructured as the special law that tuned in interests encompassing civil law, criminal law, education law, human rights and welfare law. Data and knowledge of various disputes and their resolution must be organized and shared in terms of procedural and substantive parts. A reasonable dispute resolution and sustainable follow-up management system should be established along with preventive measures.
