NASCLA acceptance in Kentucky
Kentucky does not currently accept NASCLA for statewide HBC electrical, HVAC, or plumbing licenses. Some municipalities may honor NASCLA for local GC permits, but HBC still requires its own PSI trade exams for regulated trades. Confirm the current candidate bulletin for your classification, then use timed state-specific practice instead of assuming an out-of-state NASCLA letter will transfer.
