On-the-job professional postgraduate thesis defense is the last hurdle for postgraduate degree granting. In the process of thesis defense, graduate students need to elaborate their research results and answer questions from the defense Committee. The result of thesis defense will directly affect whether graduate students can graduate smoothly. However, due to various reasons, some in-service graduate students may not be able to pass the first thesis defense. This may be because the quality of the paper does not meet the requirements, the research methods are not perfect or the defense results are not good. For these on-the-job graduate students, do they have the opportunity to apply for a second thesis defense?

In fact, whether on-the-job graduate students are allowed to apply for the second thesis defense depends on the specific regulations of schools and colleges. Some schools have clear regulations on the thesis defense of in-service graduate students, allowing students who fail to apply for a second defense. The main purpose of this regulation is to provide more opportunities for in-service graduate students, so that they can correct their mistakes, improve the quality of their papers and finally complete their studies.

In order to ensure the quality and academic integrity of papers, schools often review students' papers. Duplicate checking system is a tool to detect whether there is the possibility of plagiarism or non-citation in papers. Students need to check their papers through the duplicate checking system to ensure their originality and academic integrity.

The success of the thesis defense of in-service graduate students is often closely related to the quality and performance of the thesis. Therefore, for in-service professional graduate students, the choice and application of research methods should be taken seriously in the writing process, and the overall quality of the thesis should be paid attention to. In addition, in the thesis defense, graduate students should also actively answer the questions of the Committee and show their research achievements and abilities.
