In 1854 Dr. Đorđe Natošević, the then principal introduced gymnastics as a compulsory subject and equipped the school with several gymnastic devices.

The school's library continued its work only in 1865, when the Orthodox Church Municipality of Novi Sad assumed the responsibility to regularly finance its work. Invaluably important sources for the study of the school's history are the yearbooks that have been published since 1867. In the school year of 1867/1868 the first GCSE exams were held in the school.
