Here are the experience and exam specifics for the Certified Reliability Engineer.
Candidates must have worked in a full-time, paid role. Paid intern, co-op or any other course work cannot be applied toward the work experience requirement.
Candidates must have eight years of on-the-job experience in one or more of the areas of the Certified Reliability Engineer Body of Knowledge.

Degrees or diplomas from educational institutions outside the United States must be equivalent to degrees from U.S. educational institutions.
