1. academic quality does not meet the requirements: external audit experts may think that the paper has problems in academic research methods, theoretical basis, data analysis and so on, which does not meet the academic requirements. For example, the research design is unreasonable, the data analysis method is improper, the conclusion is insufficient or inconsistent with the research questions.
2. Incomplete or inaccurate content of the paper: External auditors may find that the content of the paper is missing or wrong, such as insufficient literature review, incomplete empirical research data and inaccurate conclusions. This may indicate that the author's understanding of the research field is not deep enough, or there is negligence in the process of writing the paper.
3. Academic ethics: External auditors may find that there are academic misconduct such as plagiarism, plagiarism of other people's research results, or data fraud. In this case, the paper will not pass the external review, because academic integrity is a principle that academic circles attach great importance to.
4. Expression and language problems: External auditors may criticize the expression and language quality of papers. If the language expression of the paper is not standardized, there are problems such as grammatical errors and unclear logic, which may affect the evaluation of the paper by external auditors.
It should be noted that different schools and majors may have different requirements and standards for master's thesis. Therefore, it is impossible to give the specific reasons for the failure of external audit in all cases. If the paper fails to pass the external audit, students should read the opinions of the external audit carefully, discuss with the tutor and relevant experts, correct and improve the problems, so as to finally pass the external audit.
