The repetition rate of graduation thesis is mainly to prevent plagiarism and academic misconduct. At present, colleges and universities adopt the method of limiting repetition rate to ensure the originality of papers.

Chongqing Institute of Science and Technology stipulates that the repetition rate of bachelor's degree thesis is less than or equal to 25%, which is regarded as passing the test and can be submitted for review or defense. If the repetition rate exceeds 25%, it will be regarded as a test failure and the author will be ordered to revise the paper. Only after passing the re-examination and examination can the paper be submitted for review or defense.
