How should an official document containing information about exams passed by a person in previous years be called? Are there any differences between "Archival record" and "Archive reference" in the context of this purpose?
An official document in such a case would be called a record. A reference can be any document or other artifact to which one refer as a source of information. The difference is the "official" nature of the document. One can use an official record as a reference in writing a book, say, but a reference does not have to be an official record of something.
