Abstract: Based on the survey of education quality in high schools in S province in China, a quantitative method is applied in this research to explore the ideal matching pattern between sleep time and high academic performance of high-school students. A multi-level warning mechanism is established for schools that sacrifice students' sleep time in pursuit of high academic achievement. The results show that “students with the highest scores when they slept for eight hours or more” was the ideal matching pattern for high-schools to ensure the healthy development of students and maintain a sound educational environment; more than 60% of schools in S province have unbalanced relationship between academic performance and sleep time. It's suggested that the administrative bodies, schools and teachers and parents should hold positive values and understand the relationship between students' sleep time and academic performance. Multi-level warning mechanisms should be in place to supervise and warn schools that blindly pursue high scores at the cost of students' sleep time.

Key words: academic achievement, sleep time, matching pattern, warning mechanism
