The class teacher rank system has been implemented in Tangyin County No.1 Middle School for nearly ten years. This system starts from the drawbacks of current class teacher management, and standardizes the evaluation and management of class teachers by hierarchical evaluation and implementation of job level management, in order to incentivize the professional development of class teachers from a systemic perspective. The core of implementing class teacher rank management is salary grading. Based on the reality, the shortage of teacher staffing has led to the heavy workload of class teachers, limited sources of grade reward funds, and incomplete overall education system. These are the main difficulties faced by the class teacher grade system, and they are also the main problems that need to be addressed in good class teacher management.
