The ISCD Certification encompasses Clinicians and Technologists in Bone Densitometry through one of three certification programs; Certified Clinical Densitometrist (CCD), Certified Bone Densitometry Technologist (CBDT), and Certified Densitometry Technologist (CDT).


The NCCA’s Standards for the Accreditation of Certification Programs were the first standards developed by the credentialing industry for professional certification programs. The NCCA Standards were developed to help ensure the health, welfare, and safety of the public. They highlight the essential elements of a high-quality program. The NCCA standards are consistent with The Standards for Educational and Psychological Testing (AERA, APA, & NCME, 1999) and are applicable to all professions and industries.

What is Certification?

Certification is the formal recognition of the specialized knowledge, skills, and experience demonstrated by existing best practices and standards in the field of credentialing. Successful programs build on a foundation of core competencies identified and updated periodically by practitioners in the field. Volunteers at all experience levels and topic specialties legitimize the program through their participation at each stage of the process. ISCD Certification is for an individual and is separate from ISCD membership.

The ISCD’s role is in developing and administering certification examinations to determine the qualifications of candidates for certification. The ISCD does not approve, endorse, or recommend any education or training programs or products designed or intended to prepare candidates for certification.

All proprietary rights in the exam, including copyrights and trade secrets, are held by ISCD. In order to protect the integrity of the exams and to ensure the validity of the scores reported, candidates must adhere to strict guidelines regarding proper conduct in handling copyrighted proprietary examinations. Any attempt to reproduce all or part of the examinations, including, but not limited to, removing materials from the examination room, aiding others by any means in reconstructing any portion of the examinations, selling, distributing, receiving or having unauthorized possession of any portion of the examinations, is strictly prohibited by law. Alleged copyright violations are investigated and, if warranted, prosecuted to the full extent of the law.

Maintenance of Certification

Maintenance of Certification (MOC) is an opportunity developed by the ISCD to streamline the requirements of recertification; track continuing education credits earned towards renewal and provide educational programs to meet the continuing education requirements. MOC is now a benefit for ISCD Members and requires no additional fees, but also is available to non-members who choose to enroll annually, in the MOC program. Staying current with the MOC program will eliminate the need to re-take and pass the certification exam.  Learn more on our MOC page.
