Accredited ISO certification is the process of certifying an organization's quality management system against the ISO standards by a certification body that has been accredited by an independent accreditation body. Accreditation is the process by which an independent organization evaluates the certification body's competence, impartiality, and performance against recognized international standards. Accreditation is critical to ensuring the integrity and reliability of the certification process. ISO certification, on the other hand, is the process of certifying an organization's quality management system against the ISO standards by any certification body, regardless of whether or not it has been accredited. The main difference between accredited and non-accredited ISO certification is the level of assurance provided by the certification. Accredited ISO certification provides a higher level of assurance that the certification body has been independently evaluated for competence, impartiality, and performance, and that the certification is therefore more reliable. Accredited ISO certification is often required by regulatory bodies, customers, or other stakeholders as evidence of an organization's compliance with the ISO standards. While non-accredited certification can still be valuable, accredited certification provides a higher level of credibility and can offer greater business benefits.
