Competitive sports have been shown to improve academic performance in secondary students. A study cited found that students who participated in competitive athletics developed better study habits and scored higher on standardized tests. This likely occurred because student-athletes had to effectively manage their time between sports and academics. Another study found that school sports participation rates and winning percentages correlated with higher graduation rates and test scores, even after controlling for other factors. Overall, competitive sports provide valuable life lessons about hard work, losing, and winning that cannot be replicated in a classroom.
