The U. S. Coast Guard's Mission Management System (MMS) is an ISO 9000-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. The NMC is compliant with ISO 9001:2015 standards.
The National Maritime Center (NMC) measures customer satisfaction by inviting customer feedback from those who have used our services.
Customer satisfaction is rated on a scale of 6 (Strongly Agree) to 1 (Strongly Disagree). Satisfied is determined by a rating of 4, 5, or 6 on the overall experience with the NMC.
Comments received in the feedback help us refine and improve our processes with the goal of continual improvement and enhancing the customer's experience with NMC services. The NMC has set a goal of 95% customer satisfaction.
Monthly Satisfaction Percent
When a credential application or required documentation is incomplete, an Awaiting Information letter is issued. The application process cannot continue until all necessary information has been received for proper review. This may cause serious delays in the issuance of a mariner's credential.
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.
