Field notes
The visible eligibility form distinguishes total hours worked from classroom hours and asks whether the user held state apprentice or trainee registration. The site says that registration can change an answer in some states, and advises users to count only hours they can document with records such as pay statements or employer letters. It also presents separate paths for reciprocity, expired-license renewal, and the licensing requirement for a plumbing-company owner.
