Typically with the DOL the sponsor of a registered electrical apprenticeship program may have language in the program document that allows the program to grant credit for prior work experience or classroom training toward apprenticeship requirements.
For example, a DOL program may evaluate and accept extensive prior experience as a licensed electrician in another city or state and grant full credit toward all the required On-the-Job Learning (OJL) competencies.
The apprentice must still be formally enrolled in the registered apprenticeship program and complete any required Related Technical Instruction (RTI), or receive approved credit for prior instruction, it would all be specified in the program’s Standards of Apprenticeship.
And that may be the catch, might be 6-months of online school or something.
Upon satisfying those requirements and any minimum participation period established by the program, the sponsor may certify completion of the registered apprenticeship, even if the apprentice did not spend four calendar years in the program.
Now if NJ would accept that or not I am not sure but my understanding is a DOL program definitely allows that.
