Effective at school
This private school itself does not have the qualification to independently issue the diploma of higher education recognized by the state, so the "diploma" issued by it is only valid within the school, only the college's own seal, so it can't be found anywhere except the school itself, including the Internet (in fact, the only website for diploma certification is the website of the only "diploma certification center" formulated by the Ministry of Education), which belongs to fake academic qualifications.
State-recognized diploma
The individual majors of this private school may have been included in the national plan. You were admitted through the normal college entrance examination, and successfully obtained the diploma recognized by the state after graduation.
Online verification
After 2002, all formal higher education qualifications can be found online, which refers to the website of the only "Academic Certification Center" established by the Ministry of Education. Find the right position and you will find the graduation certificate number.
