What can prove reading and gap?

In the internship, I will use the proof of reading and GAP.

Whether the certificate of studying is used to prove the identity of students is mainly issued by the school, and may be used to enjoy preferential policies of the state or other aspects.

However, the main purpose is to serve as a proof condition during the internship. During their junior and senior years, college students need to find an internship unit suitable for their major outside the school. Before the internship begins, the internship unit will require students to issue a certificate of study to prove their identity.
