CMD

CMD stands for Certified Medical Dosimetrist. The credential is issued by the Medical Dosimetrist Certification Board (MDCB), which describes its mission as establishing certification and continuing education standards to enhance quality patient care. MDCB also maintains a CMD verification service and a Maintenance of Certification process covering continuing professional development.

MDCB's site organizes the exam around exam development, exam scoring, exam results, and history, rather than publishing a public topic-by-topic blueprint on the homepage. The authoritative content outline lives in the Applicant Handbook. Read that handbook and the Eligibility page before building a study plan, since the tested scope and eligibility rules are set there.

MDCB publishes a dedicated Eligibility page and an Applicant Checklist, and both sit under the CMD Exam menu on mdcb.org. Because eligibility depends on your education and clinical dosimetry experience, check those pages and the Applicant Handbook directly rather than relying on secondhand summaries, then confirm any edge case with MDCB at [email protected].

Yes. MDCB states that it "makes available a practice test to be used as a study aid for the MDCB Certification Exam," and the site has a Practice Tests page. Treat it as a study aid that familiarizes you with item style and pacing, not as a predictor of your score, and use it early enough to act on the gaps it reveals.

MDCB publishes separate Exam Scoring and Exam Results pages under the CMD Exam menu. Those pages are the only reliable source for how scoring works and when results are released. This independent guide does not restate scoring rules or timelines, because MDCB revises them and any figure repeated elsewhere may be out of date.

Fees and testing windows are listed on MDCB's Exam Dates and Fees page, and application requirements are on the Exam Application page. Both change between cycles, so confirm the current cycle there before you budget or schedule. Do not rely on fee or date figures quoted in forums or older study guides.

MDCB lists both a Special Accommodations page and an International Exam Policy page under the CMD Exam menu. If either applies to you, read the relevant policy before submitting your application, because requests usually need supporting documentation and advance approval. Contact MDCB directly with questions about documentation or deadlines.

Start with the Applicant Handbook to fix the scope, then work through treatment-site planning logic, dose calculation checks, and structure contouring conventions rather than memorizing isolated numbers. Common failure modes are shallow coverage across many sites, weak grasp of plan evaluation trade-offs, and no timed practice under testing center conditions. Use the practice test to expose those gaps early.

Retake rules, waiting periods, and credential validity terms are governed by MDCB policy and are not stated on the homepage source used for this page. Check the Applicant Handbook and the Renewing Your Credentials section on mdcb.org, or contact MDCB at [email protected], before assuming a retake timeline or renewal interval.

MDCB runs a Maintenance of Certification process that it says "assures that practitioners meet the criteria for continuing professional development to protect the well-being of patients they serve and provide quality patient care." Renewal involves continuing education activities, a learning plan review, and credit reporting; see the Continuing Education section of mdcb.org for eligible activities and credit assignments.
