Medical Dosimetrist Certification Board (MDCB)

What Medical Dosimetrist Certification Board (MDCB) does

Medical Dosimetrist Certification Board (MDCB) is a non-profit certification body founded in 1988 and headquartered in Mount Laurel, New Jersey, that administers the Certified Medical Dosimetrist (CMD) credential, the recognized standard for medical dosimetry professionals in the United States. It serves approximately 5,000 practitioners working in radiation oncology and the hospitals, cancer centers, and radiation oncology departments that employ them. Core offerings include the CMD Certification Exam (a 155-question computer-based assessment administered twice annually at Meazure Learning test centers worldwide, covering seven domains led by Treatment Planning at 42%), the CE Center on the LearningBuilder platform for continuing education tracking and credential renewal, a public CMD Verification Service for employer credential checks, and a 13-standard Ethical Standards framework with formal complaint procedures. Supporting modules include practice tests via ProKnow DS integration, an Item Writing Committee program, scholarship programs, and a temporary disability leave policy.

MDCB's technology stack is built on the LearningBuilder platform, which handles exam applications, credential management, CE credit tracking, learning plan administration, and employer verification. The organization integrates with AAMD (nightly CE uploads) and ASRT (monthly CE uploads) for automated credit recognition, and with ProKnow DS for candidate practice testing. Performance-Based Testing (PBT) items were added in 2020 to measure applied clinical skills. MDCB holds NCCA accreditation through the Institute for Credentialing Excellence. The credential is mandatory under ACR, ASTRO APEx, and ACRO accreditation programs for radiation oncology facilities, creating structural demand. MDCB is professionally managed by Association Headquarters, Inc., a charter-accredited association management company, and the board includes liaisons from AAMD, AAPM, ACR, ASTRO, and JRCERT alongside at-large CMD members and a public member.

Revenue is generated through exam fees ($375), application fees ($200), annual credential renewal ($175), score confirmation ($250), certificate replacement ($25), and late/reinstatement fees. The recurring annual renewal from ~5,000 CMDs is the primary revenue base, with exam sitting fees adding variable revenue twice per year. In 2023, MDCB decided to terminate the international eligibility route after September 2025, citing procedural fairness, narrowing the candidate pool to US-trained applicants. Headcount is 1-10 employees, and the organization is privately held with no funding rounds or M&A history.

Scale indicators6 records

Recent moves7 records

Expansion highlights5 records

Broad incumbents

• American Board of Radiology (ABR): The premier physician-level certifying body for radiologists, radiation oncologists, and medical physicists. Overlaps with MDCB because ABR-certified physicists and radiation oncologists serve on the MDCB board and MDCB certificants work under physician oversight.

Emerging players

• National Healthcareer Association (NHA): Certifies a broad range of allied health professionals (pharmacy technicians, medical assistants, etc.). Comparable as a multi-credential healthcare certification body, though NHA operates across many specialties rather than a single niche like MDCB.
• American Academy of Professional Coders (AAPC): Offers healthcare-specific certifications (CPC, CRC) with exam fees, CE requirements, and annual membership/renewal. Comparable model but with a for-profit commercial orientation, contrasting MDCB's non-profit status.

Others

• American Association of Medical Dosimetrists (AAMD): The professional membership society for medical dosimetrists. Closely intertwined with MDCB through board liaison roles, scholarship programs, and automatic CE uploads to LearningBuilder — an ecosystem partner rather than competitor.
• Joint Review Committee on Education in Radiologic Technology (JRCERT): Accredits educational programs in radiologic and medical dosimetry sciences. Functions as an upstream gatekeeper that MDCB relies on for candidate eligibility — an ecosystem partner rather than a competitor.

Direct peers

• American Registry of Radiologic Technologists (ARRT): The largest US certifying body for radiologic technologists, operating a near-identical model of credentialing exams, annual renewal, CE tracking, and NCCA-accredited standards. Highly comparable as a healthcare allied-health certification organization with recurring revenue from a defined professional population.
• National Commission on Certification of Physician Assistants (NCCPA): Certifies physician assistants through a national exam and PANRE maintenance cycle. Similar in size, governance (multidisciplinary board), and NCCA-style accreditation approach for healthcare professionals.
• Nuclear Medicine Technology Certification Board (NMTCB): Certifies nuclear medicine technologists through a similar computer-based exam, CE, and renewal structure. Closely parallels MDCB in size, mission, and operating model within the radiation/radiologic sciences.
• American Registry for Diagnostic Medical Sonography (ARDMS): Certifies sonographers and other diagnostic medical specialists via standardized exams, CE requirements, and annual renewal. Comparable as a specialty healthcare certification body serving a defined allied-health professional population.
• Board of Certification for Emergency Nursing (BCEN): Provides specialty nursing certifications (CEN, CFRN, etc.) using computer-based testing, CE requirements, and annual renewal. Highly comparable operating model focused on a single allied-health specialty.
