This paper aims at exploring the values which become the basis for management practice at Gontor. The preliminary observation finds that Gontor management does not follow the mainstream management theory. It has a unique management system, and oftentimes been considered to be not standard. However, Gontor exists and gradually develops with its own unique management system. The study suggests that Gontor has its own standards which are mainly based on Islamic values. Indeed, there are a lot of values, but basically they can be simplified into the five spirits of Pondok Pesantren namely sincerity, simplicity, self reliance, Islamic brotherhood, and freedom. Each one of these spirits becomes a standard of excellence for Gontor management. Hence, vision, long term plans, organization, leadership style, and controlling are designed and practiced based on them. Finally, this paper argues that the sustainability of Gontor depends on how well the management implements these five spirits into practice. In other words, Gontor will always exist and continue to flourish and prosper if it maintains these spirits and will deteriorate by the erosion of them.
