One aspect that must be owned by a leader is integrity. Considering that currently, the Islamic-based education system is very popular in Indonesia, the purpose of this study is to identify the "Tahfidzul Qur'an" Education System (T-QES) in creating leaders with integrity. The quasi-qualitative research was conducted in two Islamic boarding schools in Bandung. The participants used is 20 participants consisting of 2 principals, 6 deputy principals, 7 "mudaris" (teachers), 1 expert and 4 "santri" (students in Islamic boarding schools) during the 2019-2021 school year. The instrument used is an open interview instrument. Meanwhile, data analysis was carried out with percentages and mapped with the help of the NVivo 12 software. The results show that the T-QES plays an important role in creating leaders with integrity. Thus, the T-QES can be one of the recommendations that can be used in an education system.
