In China, graduate students are mainly divided into full-time and part-time. Full-time graduate students enroll students through postgraduate and doctoral entrance examinations held by various institutions of higher learning, with a schooling period of at least 2 or 3 years; Before 20 17, part-time graduate students mainly refer to on-the-job graduate students, who mainly passed the 10 joint entrance examination and applied for the same academic level, and were recruited by 1 month. From 20 17 (including 20 17), on-the-job graduate students with dual certificates are uniformly named as part-time graduate students. Part-time graduate students and full-time graduate students take the national unified examination at the end of 12, draw the same score line, and get double certificates when they graduate. Institutions that recruit and train master's and doctoral students include universities with master's and doctoral programs and related scientific research institutions.

In Chinese mainland, ordinary people are used to calling master students "graduate students" and doctoral students "doctors".
