Your name is on the certificate. Prove the competence behind it.

Conformity assessment bodies, training organizations and consultancies trade on trust. The ISTO Test of Understanding benchmarks the auditors, tutors and consultants who carry your name, independently, against the international candidate population.

  • Differentiate your offering with an independent, globally recognised benchmark.
  • Evidence competence to meet accreditation requirements.
  • Standardize understanding across every auditor, tutor and consultant you field.

ISO 9001:2026 transition

The standard is changing. Is your understanding current?

ISO 9001:2026 brings a restructured Annex SL, sharper risk-based thinking and new expectations on organizational context and climate. Every certified organization will re-train. Few will verify the training worked. A misconception that survives re-training walks straight into your next audit.

What assessment and training bodies use it for

Credibility and consistency

Your service is only as strong as your least consistent professional. Verify everyone against the same eight-domain benchmark and deliver one standard of work under your name.

Market differentiation

Anyone can claim expertise. Certificates your clients can verify from a unique URL set your training or assessment offering apart in a crowded market.

Accreditation evidence

Accreditation bodies expect demonstrated competence, not asserted competence. A·C·C·U·R·A·T·E reports give independent, domain-level evidence that your people meet the bar.

Competence gap analysis

Group analytics across your auditor or tutor pool show exactly where understanding breaks down, so you can close the gap before a client finds it.
