Once designated, each CAB must keep NIST informed of all changes which may affect its status, e.g., changes in key personnel, changes in accreditation status, changes in location, legal status, or other factors which may affect the organization’s ability to perform the functions of a CAB under the referenced agreement.

Each organization nominated to become a CAB will be required to sign a statement declaring its commitment to the requirements and responsibilities of being a CAB. By signing this declaration the organization agrees to the terms of its nomination and its final designation.

To apply for CAB designation, the applicant must provide all the information listed on the web site titled "How to apply for CAB Designation under the APEC Tel MRA". All information supporting a request will be subject to review by NIST staff or a NIST-designated technical expert, both for evidence of general technical competence and claimed specific competence. Additional documentation or supporting evidence may be necessary during the review process. In some cases a site visit may be necessary.
