Mediation continues to expand, both geographically and in terms of scope. Depending on its purpose, there are three main consolidated mediation models or schools worldwide: the Traditional-Linear Harvard model, which seeks to find an agreement between the parties; the Circular-Narrative model, which apart from the agreement also emphasizes communicational aspects; and the Transformational model, more focused on relational aspects between the parties than in the adoption of agreements. The aim of this study is to determine which is the goal or purpose of mediation, confining it to the school environment and to the Spanish context. A brief comparative study is presented to this end, in which the comparative units are all the "Comunidades Autónomas" [Autonomous Regions] that make up the Spanish territory (n = 17) and the variable compared is the aim or purpose of mediation in schools as established by all the regional rules on school life (n = 17) with the force of a decree.
