IHMM’s Certified Dangerous Goods Trainer (CDGT ®) credential is awarded to professionals who have demonstrated knowledge and expertise in dangerous goods regulations by first earning the CDGP credential, and then demonstrating mastery of instructional technology and the concepts and principles of Instructional Technology (CIT certification from the Board of Certified Safety Professionals.)

Benefits of a CDGT® Credential

The CDGT ® is in the unique position of having to be a CDGP ® first, and then demonstrate a mastery of the concepts and principles of Instructional Technology (CIT certification from the Board of Certified Safety Professionals) to become a CDGT. With the CDGT, the credential holder is a teacher of others of the international regulations for the safe transportation of dangerous goods by all modes of transport.

Eligibility Requirements

A candidate for the CDGT, having already achieved the CDGP credential, has to meet the following eligibility requirements.



  1. Hold a current CDGP credential
  2. Be current in all IHMM credential fees
  3. Hold a current Certified Instructional Trainer (CIT).


Applying for the CDGT

  1. Fill out the CDGT application form here  IHMM CDGT Application
  2. To apply for the CDGT, please email the Applications and Examinations Coordinator a completed CDGT Application with the attached proof or your CIT credential.


Pay the Application Fee

Pay the application fee. There is also an annual maintenance fee.  IHMM will align your CDGT credential with your CDGP credential. This may result in a first recertification cycle of less than 5 years and the application fee will be prorated accordingly. Please submit your application and once reviewed IHMM will invoice you for the appropriate application fee. If you need assistance with the CDGT application contact Kortney Tunstall at [email protected] or call 301-244-4864

and Recognition

The CDGP® is accredited by both the American National Standards Institute and the Council of Engineering & Scientific Specialty Boards, and holding CDGP is a prerequisite to acquiring the CDGT. The CDGT itself is not an accredited credential.

Policies and

Recertification of Your Credential

Congratulations. After hard work and dedication, you earned your professional credential. Now, every 5 years you will need to recertify your valuable credential. Over 5 years you need to earn 200 certification maintenance points or CMPs. You receive 100 CMPs for the job you perform, and then need to earn a minimum of another 100 CMPs in a variety of ways demonstrating your commitment to continuous improvement and remaining current with the demands of your profession and our communities of practice.

Considering everything you did to achieve certification, don’t let it go to waste by failing to recertify.

IHMM will remind you, fairly often, about your impending recertification deadline. If you follow the steps outlined below you will find this process fairly easy to accomplish. Start with the advice in Step #1!

Step 1

Be proactive and enter your CMPs as you earn them. CMPs must be claimed following the guidelines in the IHMM Recertification Handbook.

Step 2

In your MYIHMM account, start your recertification application now to track CMPs as you go. Go to MYIHMM > then MENU > then Recertification > then Create a New Recertification Application.

Step 3

Keep your employment status and professional information current in your MYIHMM account. Please make sure your annual fees are also up-to-date.

Step 4

In your 5th year, make sure all information is correct, confirm your minimum of 200 CMPs, and submit application. Don’t worry, we’ll remind you along the way, too!

Step 5

Audits. Keep records of employment and CMPs requested. We may check in from time to time to assure accuracy.

Following these simple steps will make your recertification simple and easy to complete. Go to your online MYIHMM account, using your unique username and password.

If you have any questions about this process, please contact Jimmy Nguyen at [email protected] or Jelian Labri at [email protected] and someone will assist you.


An individual who previously held an IHMM certification that has not been decertified on ethical grounds may apply to have his or her certification reinstated if their annual fees have been expired for less than five (5) years and/or their decertified certification has been expired for less than five (5) years.

If either condition is not met, the individual must go through the full certification process to become certified again.

Reinstatement is not a reversal of decertification. All time in service is lost at the time of decertification. For more information regarding the reversal of decertification, please refer to IHMM’s Decertification Appeal Policy.

Evidence of knowing continued use of a decertified certification after having been provided notice of decertification by IHMM is a violation of your certification agreement and is unethical, and will render the individual ineligible for reinstatement.
