The duplicate checking rate of master's thesis is based on the duplicate checking rate of deleting references. Generally speaking, colleges and universities stipulate that the duplicate checking rate of master's thesis is not higher than 20%, and a few colleges and universities stipulate that the duplicate checking rate of master's thesis is not higher than 10%. In addition, Bian Xiao of paperfree told everyone that the duplicate checking rate usually refers to the repetition rate detected by the paper duplicate checking system.

1. Those whose plagiarism rate is lower than 15% can basically pass.

2. If the plagiarism rate is between 15%-30%, the tutor needs to sign it, but the problem is not serious (especially in many well-researched fields, it is not surprising that the repetition rate (or repeated inspection rate) of literature review exceeds 50%).

3. The plagiarism rate is between 30% and 50%, and it needs the signature of the school leader (it should be the college leader), which may cause big problems.

4. It is not good if the repetition rate exceeds 50%. From rewriting papers to delaying graduation.
