The aim of this study is to examine the interaction of measurement tools with various variables and among themselves by determining the effect of sports on life skills of secondary school students and the students' attitudes towards extracurricular activities. 291 secondary school students who were selected with the convenience sampling method participated in the study, and the data belonging to the study group were collected with the "Student Attitude Towards Extracurricular Sports Activities" scale and "The Effect of Sports on Life Skills" scales. Descriptive statistics, independent sample t test, one-way analysis of variance ANOVA, post hoc tests and Pearson correlation analysis were used in the analysis of the data. Research findings revealed that female participants, 10-year-olds, volleyball players and students participating in sports activities 4 times a week showed higher scores compared to other groups. On the other hand, a moderate positive relationship was found between the effect of sports on life skills and attitude towards extracurricular sports activities. It was determined that the attitude towards extracurricular sports activities significantly predicted the effect of sports on life skills. As a result, it can be said that secondary school students' attitudes towards extracurricular sports activities are effective tools in developing life skills together with participation in sports.
