A certificate of attendance is generally provided by institutions to authenticate that you have attended a certain program or been in a certain place for the mentioned period of time. In countries such as United States and Canada, schools provide a certificate of attendance to those students who have not met the criteria to get their high school diploma but have completed their tenure until the twelfth grade.
A certificate of attendance will generally contain the name of the institution issuing the certificate, the name of the person to whom the certificate is being issued, the name of the program attended by the person such as a seminar, conference or a training course, the period of time during which the person attended the particular program and the signature or seal of the authorizing entity.
A certificate of attendance acts as a proof for your claims of attending any programs for the specified period of time.
