The objective of this study is to investigate the impact of participating in the school sports on the school motivation according to selected variables. 1463 secondary school students, 790 of whom were male (54%) and 673 female (46%), participated in the study with an age average of 12,46 ± 1.23 years. The school motivation levels of the students were determined via the "School Motivation Scale for the Secondary School Students", which was developed by Kaynak, Özhan and Kan (2017), comprising of 14 articles. The data of the study were analyzed through SPSS 15 package program. The school motivation levels of the students were positively influenced from their participation in school teams, in regular physical activities, in school social activity programs, and their attendance levels to the school (p<0.05). In order to increase the school motivation levels of the secondary school students, it was suggested that they should be encouraged to participate in school teams, they should be motivated for physical activities, they should be invited to school social activity programs, and necessary measures should be taken to minimize their absence from the school.
