The standards for duplicate checking of graduate papers are not uniform, and the specific requirements depend on the specific regulations of different schools or institutions.

Most schools or institutions require that the repetition rate of graduate thesis should be less than 20%, and some more stringent schools or institutions even require the repetition rate to be less than 15% or even lower. If the repetition rate of the paper is too high, it may face problems such as being returned for revision and delaying the defense, and some strict schools may also disqualify students from defending this paper.

In the selection of duplicate checking system, the detection system of graduate thesis reuse is different from that of undergraduate thesis. For example, the first draft can use paperfree, and the final draft can use HowNet VIP5.3 system, but the specific duplicate checking rules are basically the same. The specific requirements of different schools may be different, and the specific situation needs to refer to the regulations of our school.
