Accreditation

Our certificates are accredited by an independent third party. This page explains what that means and which sectors are covered, standard by standard.

What accreditation means

A certification body is accredited when a national accreditation body confirms that it operates in accordance with ISO/IEC 17021-1. Accreditation ensures that:

  • audits are conducted by personnel qualified for the specific sector;
  • certification is clearly separated from consultancy;
  • decisions are taken impartially, by persons independent of the audit;
  • assessment criteria are uniform and traceable.

CQA is accredited by NAH (Nemzeti Akkreditáló Hatóság), the Hungarian national accreditation authority, a signatory of the multilateral recognition agreements of European co-operation for Accreditation (EA MLA) and of the International Accreditation Forum (IAF MLA).

IAF MLA: the worldwide arrangement among accreditation bodies, which extends recognition of accredited certificates beyond Europe.
