The blind evaluation system is to send dissertations without the author's name to experts who can't know the author for evaluation, so the score should be the most objective.
General colleges and universities, especially graduate schools, have relevant regulations on blind examination of papers on a regular basis, and most of them randomly select a certain number of papers for blind examination.
External auditing refers to sending papers to experts from other units for auditing. Some schools are managed by the degree office in a unified way, while others are guided by tutors. 90% of the experts appointed by the tutor submit papers for review, and they can only pass because of the good relationship between the experts and the tutor.
The right of reply can only be obtained after the blind trial and the external trial are passed, and you can't graduate if you fail to reply. As long as two experts pass the blind trial or two experts pass the external trial, they have the right of reply. The defense Committee does not include experts from external auditors, and only half of them can graduate.
Some doctors and masters can't graduate, but the proportion of masters is very small, and some have graduated, but the proportion is less than 1%. All doctoral dissertations and some master's dissertations are sent to other units for blind evaluation by the degree office before the defense, so as to ensure the quality of the defense thesis. In addition, the provincial and municipal education committees will randomly select a certain proportion of papers and invite other units to do blind evaluation to check the quality of postgraduate training.
