We require that candidates for the PhD program should have a solid and wide theoretical foundation in his/her own research field, have the ability to do scientific research and teaching, and can make creative results in science and special technology research. The candidates should master at least one foreign language, should be able to easily read references in his/her own research field, and have the ability to use the foreign language to write papers and undertake basic international communications.
Generally, the study period for PhD students is three years. If you pass all the required courses and the thesis oral defense in advance, you can apply for graduation ahead of schedule, except for those who are pursuing a same educational level or those master students who study the PhD degree in advance. If you can not finish the study schedule on time for any reason, you can apply for graduation extension which usually takes half a year to, at most, one year.
Those students, who have performed excellent in the graduate school entrance exam, can be admitted as a graduate student who studies for a PhD program directly, and whose study period usually takes five years. The direct PhD students, mentioned above, can not apply for graduation ahead of schedule. However, if one can not finish the schedule on time for any reason, one can apply for graduation extension which usually takes one year.
