The National Candidate Database (NCD) is a database of CPA candidate information created to help NASBA, Boards of Accountancy, the American Institute of Certified Public Accountants (AICPA) and testing centers protect the personal data provided by candidates during application and examination processes. As a central repository for all CPA Examination candidate information, the NCD is a global tracking system for CPA Examination candidates. With the ability to track a candidate’s history, from initial application to grading of the Examination, the NCD is a powerful tool for managing testing information.
