National Marine Electronics Association


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. It was the vision of Don Derryberry who coined the term CMET and envisioned a gold bar standard for the professional marine dealer. 

The CMET Certification program tests the knowledge base and experience of the marine electronic professional.  The test includes a variety of questions from the Federal Communication Commission General Radio Operators License to the NMEA® Installation Standard.  The CMET program is the pre-eminent certification program in the marine industry. The marine electronic technician, who has been tested, passed and awarded the CMET certificate:

  • shows to have acquired the knowledge base to diagnosis the most significant  marine electronic issues on board
  • exhibits the ability and knowledge to solve most marine electronic issues on board with effective and efficient trouble shooting
  • demonstrates an ability to design an integrated marine electronic system
  • provides the highest level of professional service

Achieving CMET recognition is no easy task.  It requires in-depth knowledge of theory, practical experience on a vessel and a high level of professionalism.

NMEA® highly recommends the following study guides - Resource Materials.  The applicant receives a pdf version of the NMEA® Installation Standards at no additional charge.

In general, there is no pre qualification required.  However, it is still required for United States applications to have their FCC General Radio Operator License (GROL) license until further notice for the following:

  • You need a commercial radio license to operate the following:  ship radio stations if; the vessel carries more than 6 passengers for hire, or the radio operates on medium or high frequencies (30 kHz or 30 MHz) or the ships sails to foreign ports, or the ship is larger than 300 gross tons and is required to carry a radio station for safety purposes.
  • You need a commercial radio license to maintain and repair the following: All ship radio and RADAR stations and all coast radio stations and all hand-carried radio units to communicate with ships and coast stations on marine frequencies.
  • A GROL license is required to adjust, maintain or internally repair FCC-licensed radiotelephone transmitters in maritime public radio services.  A GROL is required to operate the following: Any maritime land radio station or compulsorily equipped ship radio telephone operating more than 1500 watts peak envelope power (PEP) and voluntarily-equipped (pleasure) ship stations with more than 1000 watts of peak envelope power (PEP).
  • The ship RADAR Endorsement may be place on the General Radiotelephone Operator License, GMDSS Radio Maintainer's License, GMDSS Radio Operator/Maintainer License or on the First or Second Class Radiotelegraph Operator's Certificate (T1 or T2).  Only person whose commercial radio operator license bears this endorsement may repair, maintain or internally adjust ship RADAR equipment.
