About the NC Well Driller Exam
The North Carolina Well Contractors Certification Commission through NC DHHS certifies individual well contractors at Levels A–D. The closed-book written examination is specific to the certification level and addresses applicable rules, well-contractor activities, and supervision or management of those activities. Level A includes all well-contractor activities; lower levels have narrower service scopes. This program is separate from NCDEQ drinking-water operator certification, including C-Well.
Exam sponsor: North Carolina Well Contractors Certification Commission (NC DHHS Division of Public Health). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.
