ISO 9001:2008 is a quality management system designed to help organizations meet the needs of customers and other stakeholders while meeting statutory and regulatory requirements related to the product and services delivered. The standards are published by the International Organization for Standardization (ISO).

The U. S. Coast Guard’s Mission Management System (MMS) is an ISO 9001:2008 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.

What does this mean for NMC customers?

Based on the ISO 9001:2008 standard, NMC continuously monitors and improves its operations, in an effort to maintain full ISO 9001:2008 compliance.  This leads to a more consistent product (e.g., Merchant Mariner Credentials), more efficient processes, and ultimately enhanced customer satisfaction.

The National Maritime Center employs William Edward Deming's cycle of "Plan-Do-Check-Act" as its methodology for all of its processes.

PLAN - Establish the objectives and processes necessary to deliver results in accordance with customer requirements and the organization's policies.

DO - Implement those processes.

CHECK - Monitor and measure processes and product against policies, objectives, and requirements for the product and report results.

ACT - Take actions to continually improve process performance.

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.

Performance Report Information

Credentialing Performance Reports provide information on the inventory of applications at the NMC, our throughput, and our processing time for both the Medical Certificate process and the Merchant Mariner Credential process.

Note: Beginning September 2014 performance measurements for the Medical Certificates will be displayed along with the Merchant Mariner Credentialing measurements. Prior to September, figures represent combined process measurements since the NMC began issuing Medical Certificates in January 2014.

Reasons for Awaiting Information

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.

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