How to check whether a training course or certification is genuine
Accreditation, ISO/IEC 17024, regulated qualifications and practical checks that protect learners and employers from worthless certificates.

Certificates are easy to print and hard to verify. Employers, clients and learners need ways to tell genuine qualifications from worthless ones. This guide explains the assurance system and gives practical checks.
Key terms
A credential is a piece of any document that details a qualification, competence, or authority issued to an individual by a third party with a relevant or de facto authority or assumed competence to do so.5 A certification is a third-party attestation of an individual's level of knowledge or proficiency in a certain industry or profession.3 But Not all certifications that use post-nominal letters are an acknowledgement of educational achievement, or an agency appointed to safeguard the public interest.3
Accreditation
Accreditation bodies are established in many economies with the primary purpose of ensuring that conformity assessment bodies are subject to oversight by an authoritative body.1 Accreditation bodies that have been peer-evaluated as competent sign regional and international arrangements to demonstrate their competence.1 For certification of persons, the key standard is ISO/IEC 17024, which specifies criteria for the operation of a certification body for persons.2
Regulated qualifications
Some countries regulate qualifications. In England, Ofqual regulates qualifications and awarding bodies and can act on failures; for example: Ofqual fines ABRSM £150,000 over data retention failures4.
Practical checks
- Who issued it? Find the issuer's official website, not just the training provider's.
- Verify the certificate using the issuer's register, QR code or verification service.
- Check accreditation: is the certification body accredited, and by whom?
- Check validity: Most certifications are time-limited3.
- Check fit: does it cover the actual task and equipment?
- Check assessment: was there a proctored exam or practical assessment?
Warning signs
- Certificates without verification numbers.
- "Accreditation" by unknown bodies.
- Guaranteed passes or very short courses for advanced titles.
- No named assessor or practical component for hands-on skills.
Accreditation versus certification
Certification says that a person, product or organisation meets a standard. Accreditation says that the body issuing the certificate is competent. Accreditation bodies are established in many economies with the primary purpose of ensuring that conformity assessment bodies are subject to oversight by an authoritative body.1 Accreditation bodies that have been peer-evaluated as competent sign regional and international arrangements to demonstrate their competence.1 These accreditation bodies then assess and accredit conformity assessment bodies to the relevant standards.1
The international layer has changed recently: on January 1, 2026, IAF ceased operation and merged with ILAC into Global Accreditation Cooperation Incorporated.6 Older documents will still refer to IAF and ILAC arrangements.
Regulated qualifications
In education and vocational training, governments regulate qualifications. For example, the Office of Qualifications and Examinations Regulation (Ofqual) is a non-ministerial government department that regulates qualifications, exams and tests in England.7 Similar regulators or national qualification frameworks exist elsewhere, and many publish searchable registers of recognised awarding bodies and qualifications.
Warning signs: mills
A diploma mill or degree mill is a business that sells illegitimate diplomas or academic degrees.8 These businesses may claim to give credit for relevant life experience but without actual prior learning assessment programs.8 Crucially, diploma mills are frequently supported by accreditation mills set up for the purpose of providing an appearance of authenticity.8 An accreditation mill is an organization that purports to award educational accreditation to higher education institutions without requiring government authority or recognition from mainstream academia to operate as an accreditor.9 The "accreditation" they supply has no legal or academic value but is used in diploma mill marketing to help attract students.9
A step-by-step verification
- Name the claim exactly. Who issued the certificate, and which body supposedly accredits or regulates the issuer?
- Check the accreditor independently. Is it a government regulator, a national accreditation body, or a member of recognised international arrangements? Find it through official government sources, not links supplied by the provider.
- Check the scope. Accreditation applies to specific activities. A body accredited for management system certification is not automatically accredited for personnel certification.
- Search the register. Look up the provider and the course in the accreditor's or regulator's register.
- Verify the certificate. Use the issuer's online verification with the certificate number, and ask for the holder's consent if needed.
- Ask employers and clients. Who actually accepts this credential?
Red flags
- Credentials awarded for payment alone, or for "life experience" with no assessment.
- Accreditors with names similar to well-known bodies but no government recognition.
- No physical address, no named staff, or pressure to buy quickly.
- Certificates with no verification method.
- Very short courses promising advanced or chartered status.
When a course is non-accredited but still useful
Many valuable courses are not accredited, such as vendor product training or internal programmes. That is fine as long as nobody claims otherwise. Judge them on content, trainer expertise and assessment, and do not present them as regulated qualifications.
A worked example of the logic
Suppose a provider claims its "safety diploma" is accredited by an organisation with an impressive international name. Search for that organisation on the website of your national accreditation body and the international cooperation body. If it does not appear, and the government education regulator does not list it either, treat the claim as unverified. Then ask the provider directly for the scope and register entry. Legitimate providers answer quickly and specifically.
For HR and procurement teams
Add verification to the hiring and supplier onboarding process rather than relying on individual judgement. Keep a short internal list of accreditors and regulators you have confirmed, with links to their registers. Require certificate numbers on CVs for safety-critical roles. Re-verify at renewal. If a claim proves false, record it and follow your policy; fake credentials in safety roles are a serious risk, not a paperwork issue. Train recruiters to spot the warning signs listed above. The point of a mill is "accreditation" they supply has no legal or academic value9. The defence is a routine that independently checks every link in the chain.
Keep it proportionate
Spend the most effort on safety-critical roles.
Key takeaways
- Verify with the issuer, not the certificate.
- Accreditation and ISO/IEC 17024 provide independent assurance.
- Match the credential to the task.
Frequently asked questions
What is the difference between accreditation and certification?
Certification attests to a person; accreditation evaluates the body that certifies.
Is an accredited training provider the same as an accredited certification?
No. Check what exactly is accredited and by whom.
Can I verify a certificate online?
Many issuers offer registers or verification; contact the issuer if not.
Is "internationally accredited" meaningful?
Only if you can name the accreditor and confirm it is recognised; the phrase alone proves nothing.
What replaced IAF?
Global Accreditation Cooperation Incorporated, formed by the merger of IAF and ILAC at the start of 2026.
What if the accreditor is in another country?
Check whether that body is recognised by its own government and belongs to the relevant international arrangements, then whether your country or employer accepts it.
Does ISO certification of a training company mean its courses are accredited?
No. A quality management certificate covers how the company runs, not whether its qualifications are recognised.
How do I report a suspected mill?
Contact your national education regulator or consumer protection authority.
