Adult education colleges can take postgraduate exams. However, there are many limitations. College students need to graduate for 2 years or more and obtain nationally recognized academic qualifications (including: TV University, Night University, Correspondence University, Vocational College, and Self-taught Examination) to achieve the same academic ability as undergraduate graduates.

Not all colleges and universities recruit junior college students for postgraduate entrance examination. Moreover, colleges and universities have different requirements for recruiting junior college students for postgraduate entrance examination. Generally speaking, on-the-job graduate students need an undergraduate diploma to apply for a master's degree, because most of the majors of on-the-job graduate students are for undergraduate students, and only a small number of majors can be applied for by junior college students.

On-the-job people can also choose a major with the same academic qualifications as on-the-job graduate students. After completing the prescribed courses, those who meet the requirements can take the Shenshuo exam. After passing the exam, you can get a master's degree certificate. Many people get their master's degree certificates in this way, especially those on the job.
