The National Marine Electronics Association's® Certified Marine Electronics Technician (CMET) program began in the 1980’s.  Its main goal is to elevate the best and brightest marine electronic technicians in the industry.  Ultimately assure the boat owner that they have received the highest quality of design, installation and service.

The CMET Certification program tests the knowledge base and experience of the marine electronics professional.  The test includes a variety of questions from the Federal Communication Commission General Radio Operators License to the NMEA® Installation Standard. The NMEA CMET is a Marine Electronic Generalist of highest grade and should at a minimum be able to perform the following:

  • Provides the highest level of professional service
  • Design a marine electronics integrated system with proper installation and verification
  • Diagnosis of the most significant marine electronic issues on board a vessel
  • Identify the source of a marine electronics product problem

  • Understand where to get additional expert support from manufacturers and other industry sources
  • Ability to provide proper documentation to vessel owner and captain
  • Must be knowledgeable in maritime rules and regulations
  • Should own all the proper tools to perform all of the requirements above

Achieving the CMET certification is no easy task.  It requires in-depth knowledge of theory, practical experience installing and troubleshooting electronics onboard a vessel, and a high level of professionalism.
