Corruption is admitted by several scholars as the main factor causing the decline of nations. It is reasonable that this extraordinary crime disrupts all aspects of society ranging from political to social. Therefore, nowadays, all entities struggle to identify the more effective methods that lead to corruption eradication. In this regard, the education of anticorruption values is recognized as an appropriate way to prevent individuals from corruptive acts. This paper tries to examine the methods of Darussalam Gontor Islamic Institution in educating students, as an agent of change, the values of anti-corruption by dayto-day activities both inside and outside the classroom through hidden curriculum schemes. The data was obtained through interviews, observation, and documentation. Using the descriptive-analysis method, it can be concluded that there are various instruments available in Gontor for the internalization of anti-corruption values such as exemplary tiered systems, assignments to manage transparent and accountable santri organizations, strict law enforcement against dishonesty, provision of preventive disciplinary rules, habituation to standing in queues, and environmental conditioning which is full of anti-corruption messages. In addition, materials containing integrity messages are also taught implicitly in various learning materials in the classroom. Such as Al-Mahfudzat, Al-Muthalaah, and Al-Hadith.
