MRDA relies on qualified officials to make sure that its events are run safely, efficiently, and in accordance with The Rules of Flat Track Roller Derby.

MRDA has a high standard for excellence and believes that its officials should be acknowledged for having met this standard. To that end, MRDA has defined an MRDA Official as follows: “MRDA Official is an official (Ref, NSO or Announcer) who is acknowledged by MRDA as consistently and effectively volunteering their time and skills in a manner to uphold The Rules of Flat Track Roller Derby, the ‘MRDA Code of Conduct Acknowledgment, Confidentiality and Non-Compete Agreement (CCNC)’, and who supports the development and growth of MRDA.
