Questions to ask the board
- Which license level matches my experience, and do hours from another jurisdiction count?
- Is the exam open-book, and which code edition is used?
- Do I also need a city or county license where I will work?
- Is there a reciprocity or endorsement agreement with my current jurisdiction?
