Steps to Earning ISO/IEC 17043 Accreditation


ISO/IEC 17043 accreditation allows users of proficiency testing programs to feel confident that their programs are operated competently and in accordance with specified system requirements.

ANAB provides ISO/IEC 17043 accreditation as a form of assurance of compliance with international standards and recognized good practices.

Accreditation can be a long process, so it can be helpful to break it down into individual steps when considering your next move. These are the critical steps necessary to attaining your ISO/IEC 17043 accreditation through ANAB’s process:


Your first step is to request a quote from ANAB. ANAB charges for accreditation services on the basis of time spent and the number of types of proficiency tests to be accredited.


After receiving your quote, you’ll electronically submit your application, including:

  • Completed application form (including all relevant locations to be covered by the accreditation)
  • Quality manual
  • Procedures and work instructions required by the standard
  • Procedures and work instructions covering regional proficiency tests
  • Organizational structure, specifically noting the persons or organizations responsible for assigning the property values of all artifact types related to the application for accreditation
  • List of all relevant experts, if applicable
  • Completed draft scope of accreditation for proficiency test providers
  • List of artifact suppliers
  • List of suppliers of calibration or verification services
  • Example report for each proficiency test for which accreditation is sought

ANAB reviews your application to make sure it includes all necessary information, credentials, and resources.

Next Steps

Your next steps to accreditation may include an introductory visit, practice assessment, and planning visit, all of which are optional.

Accreditation Assessment

The accreditation assessment is, of course, required. After final review of your completed application, you can work with ANAB to schedule assessment dates.

Corrective Action and Follow-Up Visit

If there are findings resulting from the assessment, you’ll be required to provide corrective action, and a follow-up visit could be required. 

Accreditation Decision

After any necessary corrective action has been taken, ANAB will decide on your accreditation status. 

Surveillance and Reassessment

After you’re accredited, an annual surveillance or reassessment visit are part of ANAB’s process to ensure your continued competence and ongoing accreditation.
