Process for Verifier Approval

Prospective verifiers begin with an online application which allows them to respond to each requirement through statements of compliance and supporting documentation.  After an initial review of the application by HPDC staff, the application undergoes an audit process that may include further discussion with the applicant and review of any additional documentation that may be required.  The application and audit documentation is then reviewed by a panel made up of HPDC staff and members of the Third Party Verification Technical Sub-Group and the Technical Committee.  Final approval comes from the HPDC Technical Committee.

After approval is granted, any individual who will be conducting verifications must complete the mandatory training (if they haven’t already done so), prior to commencing work on verifications.  The verifying organization must submit the first three HPD verifications they complete for review by HPDC.  Thereafter, the verifying organization must undergo an annual audit to review their qualifications and business practices as well as having a random sampling of their verifications reviewed by HPDC.
