The Mariner Exam Modernization Act aims to improve the process for examining and credentialing merchant mariners in the United States. The main objective is to ensure that the examinations are up-to-date, relevant, and reflective of current industry standards and practices. Key provisions of the Act include changes to how the working groups that review examination questions are formed and operate. The time frame for these reviews has been extended from 90 days to 180 days, allowing for a more thorough evaluation.
