Examination Preparation

Candidates need to be familiar with relevant laws and regulations, relevant scientific principles and their application, and best management practices. Many candidates attend overview courses or use self-study materials to prepare for the examination. IHMM does not require any specific type of exam preparation or training and the exams are not based on any single reference.

IHMM credentialing programs and examinations are based on an Exam Specifications “blueprint.” The blueprints govern the competency requirements for each credential and provide the outline of topics for the examinations. Examination questions are developed from the blueprints and applicants base their examination study on the blueprint.

 Please see the Candidate Handbook for additional information

Find a Course to Prepare for the Exam

Preparing for your CDGP examination is important as the CDGP examination is challenging. Your CDGP examination is derived from the CDGP blueprint, so downloading the CDGP blueprint and understanding the domains and their contents is a good first start. If you seek a course to take in which to prepare for the CDGP examination, you will find a course in our companion foundation, the Hazardous Materials Society.

A CDGP examination preparation course may be found here.

CDGP Blueprint

A Certified Dangerous Goods Professional® (CDGP®) is a professional involved in the transport of goods and materials that have been categorized as regulated materials and have special packaging, communication, and transport requirements. The CDGP is a person who is an expert in appreciating the potential hazards and the complexity of the regulations that apply to them, and who can accurately analyze the requirements for dangerous goods transport through his or her use of regulatory reference sources. This Specification Blueprint is intended to offer guidance to candidates by outlining reasonably expected duties and tasks based on surveys of what CDGP’s do in practice.

and Recognition

The measure of the quality and strength of a certification program is to evaluate its accreditation status. Accreditation is a form of certification for the certifying organization, requiring conformance with strict standards of validity, reliability, and impartiality.

A key feature of IHMM credentialing programs, accreditation is essential because of the nature of work performed by IHMM certificants. The transport of dangerous goods is governed by model regulations published in:

  1. UN Recommendations on the Transport of Dangerous Goods – Model Regulation, 22nd Edition, 2021
  2. International Civil Aviation Organization’s Technical Instructions (ICAO TI), 2021-2022 Edition
  3. International Maritime Organization’s Dangerous Goods Code (IMDG Code), 2022, 41st Edition
  4. International Air Transport Association’s Dangerous Goods Regulations (IATA DGR), 64th  Edition, 2023 or newer may be used in conjunction with or in lieu of the ICAO TI.

Accredited credentials allow professionals to not only gain knowledge to use and implement these regulations but to be recognized for their competency to properly manage and perform the functions of the profession.

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.

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.
