Postgraduate diplomas belong to the sixth level in the international qualification structure, and belong to the same level as master's degrees. Relatively speaking, a postgraduate diploma focuses on proving students' professional ability in this field, while a master's degree focuses on proving students' academic ability in this field.
In Hong Kong and overseas, most professionals have several professional diplomas. The certificate is a formal graduation certificate, which belongs to the academic title certificate, has credits and is internationally recognized.
At home and abroad, the most important thing is to look at the international academic status of the universities that issue certificates. Graduates who study master's courses in related majors in world-renowned universities such as the University of Hong Kong or overseas universities can get partial credit exemption.
