Accreditation is widely referred to and less widely understood. These are the eight misunderstandings that surface most often, and what is actually the case.

1. Accreditation guarantees the result. It does not. Accreditation is independent evidence that the work of the certifying body was checked against a published standard. It is not a promise that nothing will go wrong at a certified organization. An accredited certificate is evidence, openly arrived at, not a warranty.

2. Certification is permanent. A certificate stays valid only while the checks behind it continue, through surveillance and recertification. A certificate with no live oversight behind it is a record of a past assessment.

3. One certificate is as good as any other. An accredited certificate rests on an independent assessment of the body that issued it. An unaccredited one rests on that body's own word, which may be perfectly sound, but is a different kind of claim.

4. The assessor who visits decides the outcome. They do not. The assessor reports findings and makes a recommendation, and a separate decision-making function decides. That separation is a requirement, not a courtesy, and it exists precisely so the person who formed the view is not the person who acts on it.

5. Accreditation checks paperwork rather than practice. Assessment includes witnessing real audits in progress, not only reading files afterwards.

6. Accreditation is the certifier's concern rather than the buyer's. It is what allows a buyer to rely on a certificate they had no part in commissioning, which makes the buyer the party it exists for.

7. Accreditation looks only at technical skill. Impartiality and governance matter just as much, because a technically capable body that cannot make an independent decision is not producing a reliable result.

8. Accreditation covers everything a body does. It does not. Accreditation has a defined scope, and the useful habit is to check that the scope covers the activity described on the certificate in front of you.
