Glossary of credential verification terms

Last checked 7 November 2026 · 10 sources

Short answer

Registers, treaties and laws use precise terms that are easy to confuse. Erasure, striking off and revocation all remove a person, but each comes from a different law 1,2 7. A caution order annotates the register 2. An apostille certifies a signature, not the content of a document 4,5. Recognition compares a foreign qualification with the home system 6. This glossary gives each term as the official source uses it.
