In Pinellas county where I took my journeyman exam around 1979 the requirements at the time were to have at least 4 years working in the trade verified by licensed electrical contractors.
In addition there was a three part exam.
1.NEC code questions.
2. calculations-VD,ohms law,etc
3. Practical trade questions- take up on a i/2 bender,Identify several componets and devices.Wire a 3way,stop start station.
In Hillsborough county they did not have a requirement but they had two terms used.
1. Journeyman- A person such as above.
2. Mechanic- Same as above but in addition had more experience and abilities.
