Before the defense, the evaluation teacher will understand and analyze the data and achievements of the defense students. Students' school grades and records are also part of the defense. It can be said that the student's identity was known before the defense.

The preparation before the defense, for the school, is mainly to do the organization work before the defense. These organizational tasks mainly include: examining and approving students' qualifications to participate in graduation thesis defense, organizing defense committees, drawing up graduation thesis performance standards, and arranging defense venues. Students who take part in graduation thesis defense must meet certain conditions, namely: 1. Must be fresh graduates who have completed all the courses prescribed by institutions of higher learning and former students who meet the relevant regulations and have been approved by the school. 2. All the courses that students have studied must be tested and passed; In a school that implements the credit system, students must obtain credits that the school allows them to graduate. 3. The graduation thesis written by students must be guided by a tutor, who signed and agreed to participate in the defense. The above three conditions must be met at the same time, and both are indispensable. Only college students who meet the above three conditions are eligible to participate in the graduation thesis defense. On the other hand, college students who meet the above three conditions, except those who are approved under special circumstances, must defend their thesis, and they are not allowed to graduate until the defense is passed.
