Certificate of completion refers to the fact that students fail in school and fail to meet graduation qualifications. The certificate of completion issued by participating in non-academic education and training only proves that a person has participated in a certain type of professional training and does not belong to the academic certificate. The certificate of completion issued by a full-time school refers to the fact that students fail in school, fail to meet graduation qualifications, or their learning institutions are unable to issue certificates recognized by national or regional educational institutions, or they should not or cannot issue graduation certificates according to state regulations. Graduation and graduation refer to students leaving school after completing their studies, but there are obvious differences between them. Graduation means that students finish their studies and leave school without a degree or certificate, while graduation means that students finish their studies and leave school with a degree or certificate. Understanding these differences is very important for students and schools.
