Do fresh graduates of the national examination have to go back to school to stamp?

You don't have to go back to school to stamp.

The fresh graduates of the national examination do not need to go back to school to stamp. As long as the general civil service examination meets the conditions for entering the examination, there is no need to provide any supporting materials. However, to participate in the Selected Graduates project, you need to apply to the organization department of the original graduation school to issue relevant certificates and seal them. College graduates who have not implemented their work units during the employment period can be treated as fresh college graduates, and their accounts, files and organizational relationships remain in the original universities or talent exchange service institutions at all levels and public employment service institutions, or they can directly participate in the civil service examination recruited by the state without going back to school to go through the formalities.
