Board of Directors

Board Service

What are the qualifications for board service?

  • Be a CMD for a minimum of 3 years
  • Have a minimum of a BS degree
  • Be a current practicing dosimetrist


What's involved?

  • CMD Board terms are 5 years in length.
  • The Board meets for two days, 3 times a year, in cities across the US and Canada.
  • At board meetings issues related to the administration of the certification exam, policy and strategic initiatives are considered.
  • Individual board members' knowledge and expertise are an important component during discussions. Each member should be prepared to discuss the issues at all meetings.
  • Each board member serves on one or more board committees: Executive, Eligibility, Ethics, Finance, Maintenance of Certification, Test Development or Nominating. Time commitment on each committee varies and may be up to 2 hours per week. Committee service is rotated annually.
  • Board members are guided through the process to submit 5 (five) exam items for each board meeting and will be awarded a maximum of 20 CE during the board term.


So why would you want to give your time and effort?

  • Quite simply, because you will be rewarded. The reward is not in funds, of course, but in other valuable currency:
  • Continuing education - learn from fellow board members from the oncology field, CMDs, Physicists and Radiation Oncologists.
  • Professional growth - gain new leadership skills that will augment your CV.
  • Interpersonal skills development - build both social and career relationships that will last for many years.
  • Pride in enhancing the profession- giving back to your community, your knowledge, expertise and time.


Applications are accepted yearly between December 1 and February 1. CMDs interested in board service or wish to nominate a fellow colleague can submit a completed application, and email it with a current CV, letter to the president indicating your service goals and two letters of recommendation to with the subject line "MDCB Board Nomination."
