Contractor Licensing Guides
If you are a contractor working toward your license, passing the required ICC contractor exam is a critical step in the process. These guides are designed to explain the exam process in plain language so you know what to expect, how to prepare, and how to avoid common mistakes that delay licensing.
Licensing requirements vary by state and city, but many jurisdictions rely on exams published by the International Code Council and administered through Pearson VUE. Understanding how these exams work before you register can save you time, money, and unnecessary retesting.
Below you’ll find step-by-step guidance organized by topic. New articles are added regularly.
