Mariner Exam Modernization Act

HR 3331, the Mariner Exam Modernization Act, updates the process for reviewing and modernizing exams required for merchant mariners (ship crew members). It extends the Coast Guard's review timeline from 90 to 180 days, creates a new working group including at least two recent exam passers, and mandates the Coast Guard to develop a plan within 270 days to update exam content and testing methods. The plan must eliminate outdated topics, modernize testing procedures, and include data collection on pass/fail rates. This bill directly affects merchant mariners who take the exams and the Coast Guard, which administers the exams and implements the changes.
