Certified Medical Investigator®, CMI Program

Are you prepared to give medical testimony?

Medical investigators are often asked to do many different things. Sometimes they must analyze a crime scene for trace evidence, other times they must review a victim, dead or alive, for signs of violence or attack, and yet other times they must analyze DNA or evidence to convict the guilty or exonerate the wrongly accused.

Why should you choose the CMI program?

The Certified Medical Investigator®, CMI program helps prepare professionals to be competent and confident medical investigators. With five distinct levels, the CMI program was developed to provide those in the forensic specialties with a base of knowledge that prepares them for the intricacies of the legal process that follow identifying and securing a piece of evidence.

What topics does the program cover?

  • The history of forensics
  • Roles of the Medical Investigator
  • Crime scenes
  • Court systems
  • Child and elder abuse
  • Drug identification

How do I maintain the CMI credential?

CMI holders must submit (30) Continuing education (CE) credits every three (3) years; or move to the next CMI level within that 3 year period.

Future CEs may be earned through ACFEI's Executive Summits and/or completing tests for the continuing education articles located in The Forensic Examiner®, provided in our online course catalog.
