The study was primarily carried out with the aim of adaptation of Fair Play in Physical Education Questionnaire (FPQ-PE). In addition, the adapted questionnaire was implemented on Turkish children and youth aged between 11 and 18 and the results were presented. The questionnaire originally adapted by Hassandra et al. for Greek students was adapted in four stages. 672 secondary and high school students from 11-18 age group participated in this study. The first stage was translation, the second stage was exploratory factor analysis for the validity of the questionnaire and the third stage was confirmatory factor analysis. At the fourth stage, the reliability was tested. Finally, another implementation was practiced on a new sample formed by 250 students from the same age group and their fair play scores were determined in terms of gender, school and class variables. The results showed that the questionnaire was valid for Turkish children and youths aged between 11 and 18, reliable except for one sub-scale and could be accepted as a practicable questionnaire. Furthermore, it was found that the main effect of gender and class of the students had significant effect on all subscales of fair play in favor of girls; at the same time, the class variable indicated a significant effect on gamesmanship and cheating sub-scales in favor of lower class (antisocial).
