Frequently asked questions

What does the Global Accreditation Board do?

GAB accredits conformity assessment bodies — certification bodies, inspection bodies and validation/verification bodies — by independently assessing their technical competence, impartiality and operational consistency against international standards.

What is the difference between accreditation and certification?

Certification confirms that an organization, product or person meets a standard. Accreditation is the independent evaluation of the body that issues those certificates, confirming it is competent and impartial to do so.
