This study aims to realize better discipline strategies for applying in high schools. We invited 400 teachers to participate the survey and collected their perceptions on the discipline strategies in terms of the acceptance of strategies and their effectiveness in schools. Based on the idea of fuzzy statistics, this study transformed the fuzzy interval data by way of fuzzy means, fuzzy centroids, and fuzzy distances to select better discipline strategies. The result reveals, in positive discipline domain, the high acceptable and effective strategies are "praise student in oral frequently", following "integrated life events in classroom management", "grant awards, small merit, and work incentives", and "leading students to participate volunteering activities"; In general discipline domain, the high acceptable and effective strategies are "notify parents to associate to solve", then "adjusting students' seating"; In special discipline domain, there is no high acceptable and effective strategies available. The selected discipline strategies might be used to improve the current issues in high schools. [For the complete proceedings, see ED557181.]
