What is accreditation?
accreditation is A process whereby a programme of study or an institution is recognized by an external body as meeting certain predetermined standards. Accreditation is often carried out by organizations created for the purpose of assuring the public of the quality of the accredited institution or programme. The state or federal governments can recognize accreditation in lieu of, or as the basis for licensure or other mandatory approvals. Public or private payment programmes often require accreditation as a condition of payment for covered services. Accreditation may either be permanent or may be given for a specified period of time.
