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.

Double-blind evaluation refers to hiding the names of authors and tutors in the works submitted for evaluation, and hiding the feedback evaluation results in the information of experts. Often used for graduate thesis review.
