Campus sports are a key link in improving the physical fitness and comprehensive development of students. With the increase in the types and scale of sports activities, schools are facing increasing legal risks, and new requirements have also been put forward for campus management. The author focuses on exploring how to identify these risks, define the legal responsibility of schools in sports activities, and develop effective risk prevention and accident response strategies, in order to establish a comprehensive risk management system within the legal framework, ensure that schools can protect student safety, safeguard the rights and interests of teachers and staff in complex environments, and promote their steady development. The identification of legal risks involves defining and classifying the types of potential risks. In campus sports activities, legal risks mainly arise from the safety of facilities, the qualifications and qualifications of faculty and staff, the safety guarantee of students, and the organization and implementation of the activities themselves. If sports facilities are not properly maintained or inspected, they may pose significant safety hazards, thereby increasing the risk of legal liability. Similarly, if teachers and staff do not receive appropriate training or qualification certification, they may cause students to be injured due to negligence when guiding sports activities, thereby putting the school at risk of legal action. The second is to evaluate the impact and consequences of legal risks. For each identified type of risk, schools need to assess the specific consequences it may lead to. By evaluating these consequences, schools can more accurately understand the severity and urgency of each risk, and thus develop more targeted preventive measures. The third is to establish a risk monitoring and evaluation mechanism. In order to effectively identify legal risks, schools need to establish a systematic monitoring and evaluation mechanism. Through continuous monitoring and evaluation, schools can promptly identify new risk factors or respond to changes in existing risk factors. The fourth is to use legal and educational expertise for risk management. Schools should utilize the knowledge of legal advisors and education experts to help identify and assess potential legal risks. Professionals can provide in-depth interpretations of current laws and regulations as well as insights into specific risks that school sports activities may face. The definition of legal responsibility is to clarify the school's responsibility in sports activities according to legal provisions. Schools need to carefully understand and comply with relevant legal regulations to ensure compliance with legal requirements in all aspects of sports activities. The second is to define specific areas and levels of responsibility. The legal responsibility of schools is not limited to the safety of material facilities, but also includes the professional behavior of faculty and the management of students. For example, schools must ensure that all physical education teachers have appropriate qualifications and are responsible for the health and safety of students in sports activities. In addition, schools should also define under what circumstances they may bear legal responsibility, such as in accidents where students are injured, schools may be held responsible for negligence or improper supervision. The third is to clarify the conditions and processes for accountability. Schools need to understand which situations in sports activities may lead to legal accountability, and establish corresponding internal review and reporting processes, including investigation, recording, and analysis of events, as well as communication with legal advisors when necessary. The fourth is to evaluate and revise existing policies and processes. In order to effectively avoid legal liability, schools should regularly evaluate policies and practices related to sports activities
