About the W12 National Standard Building Contractor (B) exam
The Level B contractor credential narrows focus to residential and small commercial projects, sitting between the entry-level C and the unrestricted Class A. While C certifications restrict scope to minor works, Class B holders can manage mid-sized builds independently. This credential demands deeper knowledge of structural compliance, site safety protocols, and contract administration than lower tiers, yet stops short of the complex project management required for Class A licensure.
