1. Education: Generally, applicants are required to have a master's degree, and sometimes they can accept applications from professionals with considerable academic level.

2. Academic achievements: Applicants are generally required to have excellent academic achievements, outstanding performance in the master's degree, high academic achievements and academic honors, experience in publishing academic papers, and in-depth research and understanding in the field of pedagogy.

3. Research Plan: Applicants need to submit a research plan or research outline, clearly stating their research direction, research methods and expected results. Show your research ability and level in the field of pedagogy. Policy suggestions for the reform of doctoral education system under the new situation should clarify the orientation of doctoral students and restore the academic value of universities.

4. Letter of recommendation: the applicant needs to provide a letter of recommendation recommended by his tutor or other experts with high academic reputation in the field of pedagogy to prove the applicant's ability and quality in academic research and academic literacy. The evaluation mechanism of doctor training does not conform to the educational law. For example, there is a compulsory publishing system in colleges and universities, in addition to dissertations, several papers should be published in so-called core journals. Taking the number of papers as the only assessment index, the direct result is that everyone is trying to make up the required number.
