This paper is to determine the influence between the role of informal leadership and the performance of school principals, specifically on the quality of culture in religious education institutions such as the Ma'arif Nahdlatul Ulama Sidoarjo Educational Institution (LP Ma'arif NU). Informal leadership refers to someone lacking a formal position, but who becomes an informal group leader, i.e. clerics or 'kiai'. The research questionnaire was put to the entire teacher population at LP Ma'arif NU. Proportional random sampling was used to question the three education levels in 18 districts. The study concluded that the role of informal leadership and principal performance together significantly influences the quality of culture in the Institution. The increased role of informal leadership, and the increased performance of principals will improve the quality of its culture. This research is important because it will benefit religious education institutions like LP Ma'arif NU throughout Indonesia, as well as units of Madrasah education or self-help schools. It will also help the self-cultivation of the Nahdliyin people, and for central and local government policies. © Primrose Hall Publishing Group.
