Generally speaking, the duplicate checking rate of undergraduate thesis does not exceed 30%, master thesis does not exceed 20%, and doctoral thesis does not exceed 10%. Periodical papers and graduation papers have different requirements for duplicate checking rate. The requirements for periodical papers are low, generally less than 20%, while the requirements for graduation papers are strict. Specific standards need to refer to the requirements of the school.
If the duplicate checking rate of papers exceeds these standards, it needs to be revised and lowered to meet the requirements of the school. At the same time, we need to pay attention to the originality and academic misconduct of the paper to ensure its quality and academic value.
In a word, the specific qualified standard of paper duplicate checking rate needs to be determined according to the requirements of schools or institutions to ensure the quality and academic value of papers.
