It is important to know the quality of a school, as an effort to choose the right school. However, problems occur when it is very difficult to find the right school according to certain criteria because there are so many choices, there are also many things to consider such as finances, location, and other parameters. This study aims to develop a decision support system model to simplify and facilitate the decision-making process in school selection. The Weighted Product (WP) model is used as a system process model, because it is considered quite simple, namely by adding alternatives and criteria used, and not being tied to other criteria. Priority scales are determined based on parameters: tuition fees, school accreditation, school facilities, distance/location, and the activeness of school extracurricular activities. Each parameter is assessed based on 5 scale levels of importance. There are 5 private high schools as samples of the data tested, and the output is in the form of a ranking list of schools according to the selected criteria, which can be used as recommendations in selecting schools.
