The aim of this study is to examine relationship between the physical education course sportspersonship behaviors and respect levels for high school students. The sample of study consists of randomly selected 505 high school students (215 female and 290 male) attending state schools in the province of Istanbul in 2016-2017 academic year. "Physical Education Course Sportspersonship Behavior Scale," "Respect Scale" and personal information form created by the researcher were used in the study. It was found that the scales was valid and reliable and could be used for high school students. Sportsmanship behaviors significantly differed according to the gender of the students (in favor of the girls), the grade (in favor of 10th grade), school success (in favor of good level) and the type of sports most interested (in favor of physically noncontact sports). It was understood that the scale scores of the students are not significantly different according to the family economic conditions. It was found that physical education course sportspersonship behaviors (Realization of Positive Behavior, Avoidance from Negative Behavior) are significantly related to respect levels (Cosmopolitanism, Communitarianism) positively. And it was seen that the level of respect was a significant predictor of the sportsmanship of the students. It is believed that the implementation of activities aimed at improving the level of respect in schools will be helpful in improving sportsmanship behaviors.
