Good answer Reno.
Here is IBEW for Mass http://ibewlocal96.org/apprenticeship-opportunities
Which has requirements and contact information assuming you go Union.
For non union http://www.mass.gov/?pageID=ocasubt...e+Examiners+of+Electricians&sid=Eoca
Here in Oregon there is a long waiting list to get in. Non union has not been accepting applications for a while now.
Union accepts as many applications as they can get for there 25$ fee getting chose is another story. Those who do get there application in can expect being in a pool of eligables. The more experience such as college or military or other training you have the better your odds to get in.
Good luck.
