ETA Master Specialty Certified Electronics Technician (CETms) exam help guide

ETA Master Specialty Certified Electronics Technician (CETms) is ETA International's master specialty credential for professionals who want to demonstrate expertise in a specific electronics technology field. ETA's Master Specialty matrix lists specialty categories such as telecommunications, fiber optics, distributed antenna systems, information technology, and RF communications, with category-specific restrictions.

ETA describes CETms as a maintainable certification. To earn it, candidates must have six or more years of combined electronics training and/or work experience, have earned the Associate CET (CETa) unless the matrix allows an approved substitute for a specialty category, hold at least six applicable certifications, and have at least four of the six in the chosen specialty category unless the current matrix states a different category-specific rule. All certifications must be current when the Master Specialty credential is requested.
