ISO 9001: 2015 Quality Management

The U. S. Coast Guard’s Mission Management System (MMS) is an ISO 9001:2015 based quality management system that was created to ensure fulfillment of national and international obligations for marine safety and security. At the outset of the mariner credentialing program centralization effort, the National Maritime Center (NMC) adopted and incorporated the MMS into its operation and has maintained compliance with the requirements listed in the ISO standard.



Customer Satisfaction Information

We measure customer satisfaction by inviting those who have received their credentials to provide feedback regarding the process of obtaining the credential. Responses are anonymous unless the responders choose to e-mail our Customer Service Center ( with more details about their experiences with the NMC.

Customer satisfaction is rated on a scale of 1 (Strongly Disagree) to 5 (Strongly Agree). The responses are averaged over the month of receipt and the results are reported.

Reasons for Awaiting Information

The most prevalent reasons for Awaiting Information delays are incomplete documentation of medical problems and professional qualifications.

As an application goes through the evaluation process, if the mariner receives an AI letter it causes delays in the processing of the application while the NMC evaluator waits for the information to be submitted. If an application is held at multiple divisions or branches the delay becomes compounded and has been as long as 300 days.

Here is a list of general reasons for requests for additional information by evaluation section, Regional Exam Centers (REC), Safety and Suitability Evaluation (SSE), Medical Evaluation Division (MED) and Professional Qualifications Evaluation (PQE).

This website contains information about avoiding AI when an application is submitted. Look for links, frequently asked questions, and tips on each webpage.
