This study aims to identify the influencing factors determining the seismic-retrofit priority before implementing seismic-reinforcement projects for elementary, middle, and high schools in South Korea. Seismic reinforcement factors of school facilities are classified into evacuation, user, facility, and local risks. The factors that affect the evacuation risks are mechanical/electrical equipment, building fire performance (fire grade), evacuation obstacles, hazardous installations, spatial distance, transportation, and playgrounds. The user-risk factors are urban and other areas, number of classes, number of students, and school ranking. The facility risks include structural factors, construction materials, building types, number of floors, and building-scale factors. The local-risk factors are the presence of fault zones and past seismic areas. The risk types and weights of the influencing factors are calculated based on a hierarchical structural model of seismic-retrofit priority. Facility risk accounts for the highest weight followed by user, evacuation, and local risks. To determine the seismic-retrofit priorities, the influencing factors are used to evaluate school facilities. This study provides the scope, index, five-point scale, and decision-making criteria for school-facility evaluation before implementation of seismic-retrofit projects. Keywords: School Facilities, Seismic Retrofit, Priority, Influenced Factor, Weight
