In Taiwan, both the academic and practitioner have noticed the disputation of high-rank civil service recruitment is getting worse due to the oral exam method. In this article, there are two research questions that need to be answered. One of them is, “How does the oral exam influence the test scores and to what degree?” The other is, “How can the oral exam be improved?” To answer these questions, the research methods of content analysis, Delphi technique, and in-depth interview were adopted. To provide persuasive evidence to disclose the serious problems of oral examination, our research chose four kinds of civil service exams as research objectives. The results of our research not only demonstrate measures for the reform of oral exam assessment but also reveal characteristics of oral exam assessment in Taiwan. Through these results, we get a better understanding of the stakeholders’ perceptions about oral examinations. Besides, it is helpful for the emergence of reinventing strategies.
