How certification works, and who watches the certifier

For ISO’s management system standards, certification is optional: a business that wants it goes to an external certification body, which audits its management system against the standard and issues a certificate where the requirements are met. While the certificate stands, a JASANZ-accredited certifier is itself under scheduled surveillance by JASANZ, which includes watching its auditors at work.

General information about how standards and certification work, drawn from the bodies quoted on this page. It is not legal advice. The rules for a particular industry or contract come from its regulator or from the contract itself, and each certification body sets out its own process.

05.1

The life of a certificate

The ISO and JASANZ pages quoted here do not set out an audit timetable for businesses. What they do describe is the shape around the audit, set out here in order.

  1. Using the standard comes first

    ISO says a business can benefit from implementing management system standards “without being certified to them”, and that certification “is not a requirement”. For ISO 9001, it lists situations in which certification is commonly requested, among them supplier approval and government tenders.

  2. Choosing a certification body

    ISO’s own suggestions for choosing one are to:

    • evaluate several certification bodies;
    • check whether it uses the relevant standard from ISO’s Committee on Conformity Assessment (CASCO);
    • check whether it is accredited, bearing in mind that “accreditation is not compulsory”.

    For management system certifiers, the relevant CASCO standard is ISO/IEC 17021-1, which covers the “competence, consistency and impartiality” of bodies auditing and certifying management systems.

  3. The audit

    In ISO’s description, certification “involves an audit by an independent certification body”, which evaluates the organisation’s management system against the standard. ISO publishes separate guidance on auditing, ISO 19011:2026, covering “internal and external management system audits”.

  4. The certificate

    Where the requirements are met, the certification body issues certification “as evidence of conformity”. A JASANZ-accredited body must apply the JASANZ Accreditation Symbol to every certificate it issues within the scope of its accreditation.

  5. The register entry

    JASANZ’s Accreditation Manual (issued 1 July 2026) obliges each accredited body to ensure that everyone it certifies within its scope is entered on the JASANZ register. The guide to checking a certificate shows how to search it.

  6. While it stands

    The manual’s definitions count “the control of surveillance or recertification audits” among the key activities of a management system certification body. The certified business also has a duty: accredited bodies must make it a condition of service that clients correct “any misleading statements made in connection with its certification status”.

  7. Changing certifier

    A business may move its certification between accredited bodies. The manual says “a valid certification under transfer remains intact during the transfer period”, that the old certifier must keep the business listed until the transfer is complete, and that a certification known to be suspended, or under threat of suspension, “shall not be accepted for transfer.”

  8. If the certifier loses its accreditation

    Its certificates stay on the JASANZ register for no more than “90 calendar days from date of withdrawal”, and the manual calls accepting a transfer from a withdrawn or cancelled body “a high risk undertaking”.

05.2

How a certifier earns accreditation

Before any of that, a certification body that wants JASANZ accreditation goes through a staged process that JASANZ publishes.

  1. Initial enquiry
  2. Formal application
  3. Document review
  4. Witness assessment
  5. On-site technical assessment
  6. Corrective actions
  7. Decision and certificate

JASANZ says applications should be made once the necessary systems already exist: “Accreditation is not a starting point for building them.” At the witness assessment, JASANZ watches the applicant’s auditors at work in the field, such as during an audit at a client site, to confirm that they “can apply their competence in practice, not just on paper.” Decisions to grant, suspend or withdraw accreditation are made by JASANZ’s Accreditation Review Board.

05.3

How the certifier is watched

Accreditation is not a single event either. JASANZ’s manual says an accredited body must undergo scheduled surveillance to keep its accreditation, and lists four scheduled activities.

JASANZ’s four scheduled surveillance activities, from its Accreditation Manual
ActivityIts purpose, as the manual describes it
Office surveillanceTo check that the assessed system keeps performing
WitnessingTo test whether the accredited body can carry out an effective audit, and to confirm that the certification decision that follows is valid
Probity testsTo test whether the accredited body works within the ethical limits of conformity assessment
Market surveillanceTo survey performance broadly, by collecting and analysing data

Office surveillance and witnessing are set out in a programme issued to each accredited body every year. On top of the schedule, JASANZ may run unscheduled surveillance, for example in response to poor performance; the manual describes the regime as “performance based”.

And above JASANZ sits one more check: to become a signatory to Global ACI’s Mutual Recognition Arrangement, JASANZ underwent peer evaluation “against internationally recognised standards”. The home page traces the whole chain.
