PISA exam aims to measure student literacy in three different areas; reading, mathematics and science. It also focuses on several characteristics of teachers and students in addition to teacher-student interaction, learning climate and order in the classroom on the base of teaching quality. The main focus of PISA 2018 was the reading skill. Besides, discipline and time management issues were also evaluated in PISA 2018 as factors that affect students’ academic performance. This study aims to examine the effect of discipline and time management issues, which were evaluated through the ST074 coded PISA questionnaire, on students’ reading performances. This study is designed in descriptive survey model. The data of the study consist of the data on the first and the last five countries with regard to reading performance in PISA 2018 with the exception of Lebanon, whose data did not exist in the database. The results of the study show that discipline and time management in classroom predicts reading performance. Also, it is concluded that discipline and time management in classroom differ in terms of the first and the last five countries with regard to reading performance, with the exception of Kosovo. The results of the study are discussed within the related literature and several recommendations are made accordingly. In this sense, countries with low reading performance are recommended to revise their educational policies in terms of discipline in classroom. In addition, teachers are recommended that they take discipline and time management issues more seriously in reading classes and plan especially their reading lessons meticulously. Also, considering that the case of Kosovon students are contradictory to the results of most studies in literature,it is recommended that researchers conduct both quantitative and qualitative studies to examine the Kosovo case in detail.
