The Certified Hazardous Materials Management Exam is given by the IHMM. The test is developed through the IHMM board and questions for the exam are submitted by active CHMMs. 
Function of the Test
The CHMM is designed to allow Hazardous Materials Managers to recertify their qualification as a Certified Hazardous Materials Manager. Candidates have a Bachelor’s degree in hazardous materials management, environmental sciences, a physical science, or a related field as well as a minimum of four years in hazardous materials management. This test is for individuals employed within the United States and all applications for the certification are required to be made every 5 years.  There are currently 15,000 CHMMs across the world all of which have professionally advised on the proper handling and management of hazardous materials in order to ensure safety and compliance with industry regulations. 
The CHMM is tested through Kryterion HOST Network, which has 650 facilities across the world. Testing is done through a computer format and is given on an on-demand basis by Kryterion HOST Network. For the first time a candidate takes the CHMM, total fees amount to $675, which includes the application fee, examination fee, and annual certification maintenance fee for the first year. 
The CHMM requires recertification to be taken every five years from the date the last certificate was issued. The candidate does not have to pay the IHMM for recertification if he or she can provide required documentation, however if he or she decides to recertify by exam, the cost is $360 payable to the IHMM with a late/expired fee of $25 (if applicable). In order to recertify for the CHMM, the candidate must have at least 200 Certification Maintenance Points (CMPs) during a five year time scale. There is a long list of where CMPs come from, however different qualifying activities allow the candidate for the CHMM to earn more CMPs than other activities.
Recertification costs $175, non-refundable after submitting the application .
Retaking the CHMM
A candidate may retake the CHMM two times after submitting a Retake Form without penalty. However, after a third failure to pass the CHMM, the candidate must wait 12 months before taking the test again.

- Sample Certified Hazardous Materials Management Exam Questions:
- The U.S. Department of Transportation (DOT) defines a combustible substance as
- A. a substance with a flashpoint of no more than 60°C or 140°F.
- B. a substance with a flashpoint of more than 60°C or 140°F, but less than 93°C or 200°F.
- C. a mixture that contains a substance with a flashpoint of more than 60°C or 140°F that has been mixed with a substance with a flashpoint of less than 60°C or 140°F when the mixture is transported at a temperature less than the flashpoint of both substances.
- D. a substance with a flashpoint of more than 93°C or 200°F.
- A Risk Management Plan (RMP) analysis in which an organization attempts to create a series of procedures that a facility can use to respond to the release of a hazardous substance for a situation in which the hazardous substance does NOT spread as far as possible is known as
- A. a process hazard analysis.
- B. an offsite consequence analysis.
- C. an alternative release scenario analysis.
- D. a worst-case scenario analysis.
- A hospital is attempting to determine the appropriate way to dispose of a piece of medical equipment that has been classified as a Class A low-level radioactive waste, but only has a half life of approximately three days. The hospital is required to
- A. isolate the equipment until the radioactive atoms completely decay and then trash it.
- B. bury the equipment so that it is no less than five meters from the surface until the radioactive atoms completely decay.
- C. turn the equipment over to a low-level radioactive waste disposal facility.
- D. isolate the equipment in a pool of water in a secure, contained space until the radioactive atoms completely decay.
- There is evidence to indicate that PCBs may have a significant environmental impact because they can
- A. damage the ozone layer.
- B. exist naturally in the environment, but may also be found in many homes and buildings.
- C. be used to build pipes and, as a result, may contaminate drinking water.
- D. build up in the soil near a body of water and contaminate fish living in that water.
- The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) is
- A. a federal statute that grants the Environmental Protection Agency (EPA) the ability to identify the individuals that are responsible for the hazardous release of a substance, the ability to compel the individuals responsible to clean-up the release even if the individuals are no longer using the site, and the ability to fund clean-up operations if it is impossible to identify and/or compel the individuals who are responsible.
- B. a federal statute that grants the EPA the ability to establish hazardous waste regulations so that the EPA can monitor and control hazardous waste throughout the waste stream.
- C. a federal statute that requires oil facilities to have plans in place to prevent, fund, and clean-up oil spills.
- D. a federal statute that is designed to encourage each facility to reduce the amount of pollution that the facility generates by requiring the facility to disclose to the public information about the amount of pollution that the facility creates.
- An Environmental Management System (EMS) typically has all of the following benefits EXCEPT:
- A. It is relatively inexpensive to implement and will only require a relatively small investment of resources.
- B. It can reduce the total material and waste management costs that the company will be required to pay in the future.
- C. It can improve the company's image with the public and the company's relationship with regulatory and law enforcement agencies.
- D. It can help the company to reduce the risk of an incident and/or a violation, which, in turn, may help the company avoid the penalties, fines, and increased insurance rates that typically accompany an incident or violation.
There are a total of 140 multiple-choice questions on the CHMM exam, with the final score based on a pass/fail basis. There is no penalty for attempting to answer all questions.
