Different degrees have different requirements for the duplicate checking rate of papers. For example, the duplicate checking rate of undergraduate graduation thesis should not exceed 30%, the master thesis should not exceed 5%- 15%, and the application for excellent master thesis should not exceed 5%.
Only after certain conditions are met can repeated detection be carried out. For example, for papers in professional journals, the duplicate checking rate is less than 30% for first-class papers, less than 25% for intermediate/provincial papers, less than 20% for advanced/national papers, and less than 8%- 15% for advanced/core journals.
In addition, some periodical publishers, schools or institutions may have stricter duplicate checking standards, such as less than 10% and less than 5%.
Please note that the above values are only approximate, and the specific situation will vary according to the requirements of specific schools or institutions.
