Electronics Associate DC (EM1)
Credential: Electronics Associate DC (EM1)
Credentialing Agency: Electronics Technicians Association, International (ETA-I)
Renewal Period: 4 years
The Electronics Technicians Association, International (ETA-I), Electronics Associate DC (EM1) is an entry-level credential designed for technicians in the electricity and electronics field. The EM1 can be a stand-alone certification for candidates requiring a narrower set of knowledge and skills or it can be part of the EM program, which requires that candidates attain five modules towards the eventual goal of achieving ETA’s Associate level certification (CETa). Candidates must pass a written examination.
More information can be found on the certifying agency's website.

RECERTIFICATION
Electronics Associate DC (EM1)
Renewal Period: 4 years
Additional considerations for the Electronics Associate DC (EM1) include:
- To provide a path for the technician leading to the Associate CET (CETa) credential, the five BASIC modules of the Associate CET can be acquired individually through the Electronics Modules (EM1-5) program. Once a technician attains all five module certifications, ETA issues an official Associate CET certification. Note that all five EM modules must be current.
