MRO Resources

Medical Review Officer (MRO) and Medical Review Officer Assistant Courses

A Medical Review Officer (MRO) is a critical part of federally mandated drug testing programs. They are entrusted with the responsibility of safeguarding the tested individual’s rights while also contributing to health and safety in the workplace. With advances in technology and regulatory changes, not to mention new forms of substance abuse, the field is constantly evolving.   
ACOEM has the resources you need to prepare for the MRO initial certification along with recertification, which takes place every five years.

Today, physicians in many specialties conduct drug and alcohol tests for business, industry, government agencies, and schools. The need for trained medical review officers (MROs) to evaluate test results extends to more than 20 million Americans. The Drug-Free Workplace Act affects all federal agencies. Mandatory alcohol and drug testing is now required of all intrastate truckers, commercial driver’s license holders, and other transportation workers. In joint government agreements, the United States, Canada, and Mexico also monitor truckers crossing international borders. More than 60 percent of large private employers require drug and alcohol testing. ACOEM has been the educational provider of choice for MROs since 1990. More than 18,000 physicians have completed ACOEM’s highly acclaimed training.
