If the primary school fails, the file (student status) shall be kept for one year, and the year shall be written for one more year. Compulsory education is a basic public service with the characteristics of equality, fairness and compulsion, so in principle, repetition and skipping classes are not encouraged. The problem of repeating a grade or skipping a grade is a specific student management problem, which is the change of student status. According to the Measures for the Administration of Student Status of Primary and Secondary School Students, the conditions and handling requirements for repeating or skipping grades are stipulated by the provincial education administrative department.
