The process of officially recognizing or approving an organization, school, or individual as meeting certain standards or qualifications.
The university received its accreditation after a thorough evaluation by the accrediting body.
Accreditation is formed from "ad-" (meaning to or toward) and "creditus" (meaning trust or belief). The term refers to the process of granting approval or recognition, thereby establishing trust in an institution or program.
Think of 'trust' ('creditus') being given 'to' ('ad-') an institution, which helps you remember that accreditation means official recognition or approval.
