A diploma is a certificate or deed issued by an educational institution, such as college or university, that testifies that the recipient has successfully completed a particular course of study.

The diploma (as a document certifying a qualification) may also be called a testamur, Latin for "we testify" or "certify" (testari), so called from the word with which the certificate begins; this is commonly used in Australia to refer to the document certifying the award of a degree. Alternatively, this document can simply be referred to as a degree certificate or graduation certificate, or as a parchment. The certificate that a Nobel laureate receives is also called a diploma.
The term diploma is also used in some historical contexts, to refer to documents signed by a King affirming a grant or tenure of specified land and its conditions (see Anglo-Saxon Charters and Diplomatics).

In the United States, the word diploma usually refers to the actual document, especially in the context of academic degrees earned at the college or university level. That is, Americans normally draw a distinction between a diploma as documentary evidence of the award of an academic degree, and the underlying degree itself (which is not called a diploma). The reason this distinction matters is that many American universities do not print diplomas until several weeks or months after the dates on which graduates were formally awarded their degrees on their academic transcripts. In other words, when a diploma says on its face that so-and-so degree was "given at [city] on [date]", the diploma itself was not physically handed to the holder on that date. (For ceremonial purposes, the documents handed out at graduation are simply certificates of participation in the graduation ceremony itself.) Thus, asking alumni when they received their diplomas is usually pointless; what really matters for most purposes (e.g., occupational licensing) is when they received their degrees. This important distinction can lead to some confusion when persons who obtained degrees at American universities are presenting their academic credentials in other countries.
There are two major exceptions where Americans have merged the document with the qualification it represents (as seen in other countries). The first is the high school diploma. Second, the term "diploma" can refer to a specific academic or training award. For example, the Diploma in Nursing was offered by hospital-based nursing schools.
Historically, American universities emulated their European counterparts by issuing diplomas written in the Latin language. That is now the exception today: "While most colleges and universities now issue English diplomas, some prominent holdouts -- including Yale, Princeton and the University of Pennsylvania -- still use Latin."
The term diplomate (always ending with an e) is used in the United States to refer to a person holding a specialized certification in a professional field, although the documentary evidence of this is traditionally called a "certificate" and not a "diploma". For example, board-certified physicians in the United States traditionally indicate their board-certified status on their letterhead and business cards with the title "Diplomate", a comma, and then the name of their certifying board.
It has not been practice for UK providers to issue degree certificates in Latin for at least 10 years. Contemporary certificates are in English. Latin versions are occasionally issued as mementos, but are supplementary to the English version.
