Doctoral dissertation is an important symbol to comprehensively measure the quality and academic level of doctoral students. It should be completed independently by doctoral students under the guidance of tutors, and doctoral students have been engaged in dissertation research for at least two years. The doctoral thesis should show that the author has a solid and extensive basic theory, systematic and in-depth professional knowledge and related subject knowledge; Have the ability to conduct scientific research independently; Make creative achievements in science and technology or professional and technical work.
For long-term graduate students who have not passed the doctoral thesis defense (studying for a doctoral degree in advance, continuing to study for a doctoral degree, and 3+2+3 graduate students), if their school status is terminated and they drop out of school, the school can issue a doctoral diploma. If I think that even if I postpone graduation, my thesis can't meet the requirements of doctoral degree after revision, and the defense committee thinks that my thesis has reached the level of master's degree in the same major, I can change to master's degree in the original major with the consent of my tutor and college after applying, and change to master's degree thesis according to the requirements of master's degree, and participate in the evaluation, defense and review of master's degree thesis again. Once the postgraduate status is changed to a master's degree, you may not apply for a doctor's degree. If the master's thesis defense still fails, the school can only issue a certificate of completion to the master.
