I am a Postgraduate Student in Educational Management Doctoral Program. I am interested in doing research in the field of Education Management, specifically educational and educational leadership and culture. This article I publish is a new finding in the development of educational leadership approaches in Indonesia. The principal's humanistic approach is the key to school success in optimizing character education strengthening programs. Without the inculcation of humanistic values, the formation of character will not be integrated with the existence of humanity. By forming character means building awareness of humanistic values in students. In addition, there are two reasons behind the school principal using a humanistic approach, namely; a) personal characteristics (personal excellence) of the principal. The two principals found in the study were members of the Catholic Spiritual Congregation (nuns / spiritual women) who possessed integrative humanistic personal wealth. b). inspired by the spirituality of life of the founder Mother of the Catholic Spiritual Congregation who carries out missions in the field of education. Furthermore, the findings of this study represent a new approach in the leadership of principals to overcome problems in implementing character education strengthening programs in Indonesia.
