Practice Tests
The Medical Dosimetrist Certification Board of Directors (MDCB) makes available practice tests to be used as an aid in studying for the MDCB Certification Exam. The practice tests are composed of sample questions that reflect the test matrix. Successful completion of practice tests does not predict successful performance on the CMD exam.
Practice tests are intended to be a supplement to exam preparation. Although the questions in the practice tests are representative of topics covered on the exam, they do not fully address all the categories and sub-categories of the exam matrix domains. Practice tests previously made available may include detail that is no longer reflective of current exam content.
Exam candidates should be familiar with popular textbooks covering subjects in radiobiology, physics, dosimetry, cross-sectional anatomy, and principles of radiation oncology practice. Questions are also drawn from reports that are relevant to current dosimetry practice published by the AAPM, ABS, ASTRO, ICRU, ICRP and NCRP as well as published RTOG clinical trials and NCCN guidelines.
