Lack of students' abilities in reading Al-Qur'an hampers the learning process of Islamic Religious Education (PAI -- "Pendidikan Agama Islam") in universities. Ironically, this fundamentalism has not been able to be resolved at the previous level of education. Various methods of reading Al-Qur'an have been compiled, but in fact, there are still many students who have not been able to read Al-Qur'an. Hence, this research aims at analyzing the implementation of the TAHQIQ learning model in order to improve Al-Qur'an reading skills. This research employed the action research method. The research subjects were 360 prospective primary school teachers in one of the universities in Sumedang Regency, consisting of 130 male and 240 female prospective teachers. This research revealed that the TAHQIQ learning model was able to improve the students' abilities in reading Al-Qur'an to reach the level of "Jayyid" in 12 meetings. Therefore, it can be concluded that the TAHQIQ learning model was able to eradicate students who were Al-Qur'an illiterate.
