The words Certification and Accreditation might seem like they refer to the same thing, but in the assessment world, they are quite different. Certification refers to the process of attesting to the skill of a professional, like taking an exam to be certified as an accountant. Accreditation is the process of attesting that a program or entire organization meets certain quality standards. So here, we are putting a stamp of approval on a certification that it is accredited to be high quality. The two primary organizations that do this are NCCA and ANSI.
