Is ISO Accreditation different from Certification?


In the ever-evolving business landscape, organisations strive to meet international standards to ensure quality, efficiency, and customer satisfaction. Amidst the array of globally recognised benchmarks, ISO (International Organisation for Standardisation) standards stand out as pillars of excellence. However, the terms “ISO accreditation” and “ISO certification” are often used interchangeably, causing confusion among businesses and consumers alike. This blog aims to unravel the intricacies surrounding ISO accreditation and certification, emphasising the distinctions between these two crucial concepts and shedding light on their respective roles in organisational excellence.

Understanding ISO Certification

ISO certification is a formal recognition that an organisation complies with specific ISO standards, signifying a commitment to quality management and continuous improvement. This certification is typically granted by external certification bodies, also known as registrars or conformity assessment bodies, following a meticulous evaluation of the organisation’s management system, processes, and documentation.

Key ISO certifications include ISO 9001 (quality management), ISO 14001 (environmental management), and ISO 27001 (information security management), among others. Achieving ISO certification demonstrates that an organisation has established and maintained effective systems aligned with the chosen standard, instilling confidence in customers, stakeholders, and partners.

The Certification Process

The journey toward ISO certification involves a structured process:
Pre-Assessment: Organisations conduct a preliminary assessment to evaluate their readiness for certification, identifying areas that may require improvement.
Documentation: Comprehensive documentation of processes, policies, and procedures is prepared to showcase adherence to the specific ISO standard.
Internal Audit: An internal audit is conducted to identify and rectify any non-conformities before the external certification body’s assessment.
External Audit: A certification body, accredited to perform ISO assessments, conducts a thorough evaluation of the organisation’s compliance with the relevant ISO standard.
Certification Decision: Based on the audit findings, the certification body decides whether to grant ISO certification.

Understanding ISO Accreditation

ISO accreditation, on the other hand, pertains to the formal recognition of a certification body’s competence to perform ISO certifications. Accreditation is granted by an accreditation body, an independent organisation responsible for assessing and ensuring the competency of certification bodies.
Accreditation serves as a quality assurance mechanism, ensuring that the certification process is conducted impartially, competently, and consistently. An accredited certification body has demonstrated its ability to uphold the standards set by ISO and the accreditation body, providing an additional layer of credibility to the certifications it issues.

Key Differences

Scope of Evaluation:
ISO Certification: Primarily evaluates an organization’s adherence to specific ISO standards, such as ISO 9001, ISO 14001, or ISO 27001.
ISO Accreditation: Focuses on assessing the competency of certification bodies to conduct certifications across various standards.
Issuing Authority:
ISO Certification: Issued by certification bodies after successfully assessing the organization’s management system against the relevant ISO standard.
ISO Accreditation: Granted by accreditation bodies to certification bodies, signifying their competence and adherence to ISO/IEC 17021 (Conformity Assessment – Requirements for Bodies Providing Audit and Certification of Management Systems).
ISO Certification: Demonstrates an organization’s commitment to quality, compliance, and continual improvement, instilling confidence in stakeholders.
ISO Accreditation: Ensures the credibility and reliability of certification bodies, fostering trust in the certification process itself.
ISO Certification: Involves the assessment of an organization’s internal processes, systems, and documentation against specific ISO standards.
ISO Accreditation: Focuses on evaluating the competence, independence, and impartiality of certification bodies, validating their ability to conduct certifications reliably.

The Interplay Between Certification and Accreditation

It’s crucial to recognise that ISO certification and accreditation are interconnected in shaping a robust quality management ecosystem. Organisations seeking ISO certification often choose certification bodies that hold ISO accreditation. The accreditation process scrutinises the certification body’s competence, ensuring that it adheres to international standards for conducting assessments.

In essence, the relationship between certification and accreditation can be likened to a chain of trust. ISO accreditation provides assurance that the certification body is competent and operates impartially, while ISO certification demonstrates that the organization meets the specified standards. Together, they create a seamless, reliable framework that promotes quality and consistency in diverse industries.


In conclusion, the journey toward ISO excellence involves two integral components: certification and accreditation. ISO certification signifies an organisation’s commitment to meeting specific international standards, instilling confidence in its stakeholders. On the other hand, ISO accreditation ensures the competency and credibility of the certification bodies, fostering trust in the certification process itself.

The distinctions between ISO accreditation and certification are nuanced but pivotal for organisations aiming to navigate the complex landscape of international standards successfully. As businesses continue to prioritize global best practices, a clear understanding of these concepts becomes paramount. By demystifying ISO accreditation and certification, organisations can not only enhance their quality management systems but also build enduring trust with customers and partners in an ever-evolving marketplace.
