There are many problems in the academic standards for bachelor’s thesis,which have attracted wide attention from colleges and society. This paper investigates the overall situation of the repetition rate detection of bachelor’s thesis through questionnaire,and proves the rationality and effectiveness of the repetition rate detection system. Through comparing the results of the same five papers with five mainstream repetition rate detection systems,the limitations of the detection system are demonstrated and the reasons are analyzed. The dissertation detection system plays an important role in the detection and prevention of undergraduate academic misconduct,but it also has some limitations. In order to effectively improve the academic standardization of bachelor’s thesis,it is necessary to adhere to the ideas of prevention in advance,control in the process and governance afterwards,constantly strengthen and deepen academic integrity education and writing standard education,actively play the guiding role of tutors,and take a reasonable look at the test results of the repetition rate of bachelor’s thesis.
