Why Hire a CMD?
Why Hire a Certified Medical Dosimetrist (CMD)?
Hiring a non-Certified Medical Dosimetrist is comparable to hiring a non-board-certified physician or physicist. Organizations and institutions should prioritize hiring a Certified Medical Dosimetrist to ensure they are providing exceptional care to their patients, current with state-of-the-art technologies, and up-to-date with rapidly changing advancements within the field. Rapid evolutions in the field combined with the complexities involved with developing comprehensive treatment plans for patients undergoing radiation therapy has led to the need for a deeper, fundamental understanding of the physics behind dosimetry and the advanced technology used in the field.

The MDCB exam is accredited by the National Commission for Certifying Agencies (NCCA). Development of the examination itself follows a rigorous process that adheres to best practice standards outlined in the Standards for Educational and Psychological Testing developed jointly by the American Educational Research Association, American Psychological Association, and the National Council on Measurement in Education and which Prometric is devoted to maintaining.
The examination continues to be updated for relevance to current practice through a Job Analysis Survey conducted every 5 years by Prometric, the MDCB exam administrator. The Job Task Analysis also known as a Role Delineation Study is designed to meet stringent certification industry standards and recognized best practice guidelines.
As a result of the Job Task Analysis, a test matrix is delineated. The most recent Job Task Analysis outlines the following content areas and percentages:
2019 Exam Matrix
- Treatment Planning - 40%
- Radiation Physics - 16%
- Dose Calculation Methods - 15%
- QA & Standard of Care - 8%
- Brachytherapy - 6%
- Localization - 8%
- Radiation Protection - 7%
