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, yet other times they must analyze DNA or other 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, including 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?

The Certified Medical Investigator® Program requires Certified Members to obtain 30 Continuing Education Credits every 3 years. Excess credits obtained during that 3 year period will not be applied to the following recertification window.

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.
