Benefits of a CHMM® Credential

Employers face an increasingly challenging task of proving their regulatory compliance and safety to suppliers, customers and enforcement agencies. With a CHMM®, not only are you personally recognized for your competence in the laws and regulations of hazardous materials, but it demonstrates the company’s high standard of regulatory compliance, as well. With demand for CHMM® professionals, the credential positions you for a career of growth and impact.

Furthermore, under federal regulation 40 CFR § 312.10, the United States Environmental Protection Agency defines the IHMM CHMM as an “Environmental Professional.”

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 CHMM examination is important as the CHMM examination is challenging. Your CHMM examination is derived from the CHMM blueprint, so downloading the CHMM 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 CHMM examination, you will find a course in our companion foundation, the Hazardous Materials Society.

A CHMM examination preparation course may be found here.

CHMM Blueprint

The CHMM examination is a testing instrument designed to evaluate candidates seeking professional certification in the field of hazardous materials management. This Specification Blueprint is intended to offer guidance to candidates by outlining reasonably expected duties and tasks based on surveys of what hazardous materials managers do in practice. As your CHMM examination is drawn directly from the CHMM blueprint, if you understand the blueprint you will understand what is on your CHMM examination.

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 handling and management of hazardous materials and the transport of dangerous goods are governed by model regulations published by the US Environmental Protection Agency, US Department of Transportation, committees of the United Nations as well as a network of state, national and international organizations.

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.
