Blind evaluation is a Chinese character, and its pinyin is máng shěn, which refers to a system of organizing expert group evaluation, that is, submitting evaluation anonymously, which means that the evaluation tutor does not know who the author of the paper is. In this way, the false positive rate of scores is low, which is generally used in college marking.
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. Colleges and universities in general, 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, while others are guided by tutors. 90% of the papers are submitted by experts appointed by the tutor.
The proportion of blind examination of master's thesis in different schools is different, generally between 30% and 50%. Doctoral dissertations are all blind, and of course there are those who can't graduate. Especially good schools pay more attention to the quality of postgraduate training.
Shanghai draws a certain proportion of applied graduate students to participate in the blind trial. Doctoral students are subject to compulsory blind trial. As long as they apply for a doctoral degree, they must participate in blind trial. Blind evaluation means that the content and topic of the paper can't involve your tutor's name and your name. Generally, it is sent to foreign schools for review, and the reviewers will not know who this paper belongs to and who is the instructor of this paper.
So it's called blind trial. Blind tests, especially doctors, must be taken seriously, but then again, taking them seriously will basically pass (master's thesis). The doctoral thesis itself requires high academic level, so it is difficult to pass.
