STUDY THE WAY THE EXAM WORKS
The electrician practice test here is multiple choice, same as the real thing. Tap an answer and the explanation appears immediately with the rule behind it. Miss one and smart review puts it back in front of you before you forget it — that is what turns a nec code quiz into real retention.
The timed mock exam runs full length against the clock, so exam day is not the first time you have sat one. Journeyman and master electrician candidates each get their own format.
LICENSED IN YOUR STATE
Electrician licensing is state business, so this electrical exam prep serves candidates in texas, california, florida, ohio, north carolina, georgia, virginia, michigan, washington and oregon alike — and everywhere else. There is no national electrician exam: question count, time allowed and the pass mark are set by your state or city licensing board, and this app says so. Check your licensing board before exam day.
WHO IT IS FOR
Apprentices sitting the journeyman electrician test for the first time, and working wiremen going for the master electrician license — anyone wanting an electrician practice test and a nec code quiz that fit in a lunch break with no signal.
