One of the modernisation movements in the 19th century of the Ottoman Empire was the setting up of rüştiye schools. The first of these was the one which was opened in Davut Pasha School in İstanbul, by Ahmet Kemal Efendi, in 1847. Following the success of this first initiative, the number of rüştiyes was increased. In 1863, there were 13 schools in Istanbul, one of which was for girls. The other 48 rüştiyes were located in the provinces, and The Maarif-i Umumiye Regulation published in 1869 was influential in this propagation. When in 1873, the number of rüştiyes had reached 307, throughout the country, and at the end of the Sultan Abdülhamid II era, this number became 619. Rüştiye school in Gaza, the subject of this article, was one of them. This study, based on the Ottoman archival documents, examines the opening of Gaza Rüştiye School, the early staff appointed there, provisions of teaching materials matching the modern standards, and rewards given to the teachers. The other point examined is to detect the academic achievements of the students via the exam tables inherited from this school. Within this context, it has been tried to present an instance of an institutional educational history study of the Gaza Rüştiye School, specific to the effort to establish a modern educational understanding in Gaza town.
