Michigan requires a 70% passing score on a written NIUPLE-administered exam for boiler operator licensing. LARA classifies licenses as high-pressure or low-pressure, and each classification requires its own written examination. Candidates must document relevant operating experience before sitting for the exam. Michigan does not automatically accept out-of-state licenses — you must apply through LARA and pass the Michigan-specific exam.

The state requires separate licenses for high-pressure and low-pressure boiler operation.

Frequently Asked Questions
How does Michigan administer the boiler operator exam?
Michigan uses the National Institute for Uniform Licensing of Power Engineers (NIUPLE) to administer boiler operator exams. You must apply through LARA's Bureau of Community and Health Systems, which will authorize you to schedule and take the NIUPLE written exam.
What are the boiler operator license classifications in Michigan?
Michigan issues separate high-pressure and low-pressure boiler operator licenses. High-pressure covers steam boilers operating above 15 psi and hot-water boilers above 160 psi or 250°F. Low-pressure covers boilers below those thresholds. Each classification requires its own written exam.
Does Michigan accept out-of-state boiler operator licenses?
Michigan does not automatically accept out-of-state licenses. You must apply through LARA, document your operating experience, and pass the NIUPLE exam for the appropriate classification level.
What experience is required for a Michigan boiler operator license?
Michigan requires documented operating experience under a licensed boiler operator. The specific hours vary by classification level — high-pressure licenses require more experience than low-pressure. All experience must be verified by your supervising engineer on the LARA application.
