Generally speaking, for the sampling inspection of master's thesis, the requirements of each school are different. Some schools may randomly take about 20% of all students' test papers for re-testing, which is sampling inspection.

However, there is no specific standard for paper sampling. The specific standard depends on how your own school stipulates it. Moreover, if your own paper passes the duplicate check, the final paper will be sampled by you, and if it fails, it will have a certain impact on yourself.

The sampling inspection of master's dissertations is conducted once a year, covering the dissertations awarded doctoral and master's degrees in the previous academic year, and the sampling inspection ratio of master's dissertations is about 5%.

Each sampled dissertation was sent to three peer experts for review, and the experts commented on the dissertation according to the requirements of different degree types. Experts' opinions on the sampling of dissertations should be made public in an appropriate way.
