Applications for licensing are managed by your local city or county government jurisdiction. Those agencies determine which ICC exam is appropriate for your license based on local code adoption. They also determine if pre-authorization is required.
To find the details of the sub-categories listed, you must use the ICC web page (from the button below) and search for your exam by choosing "Type: Contractor/Trades" and "State: National/All". Then enter the three digit exam code in the "Title" (e.g., T16). Click "Search" then "Outline".

NOTE: The content above for "Plan Reading" is not part of the NEC. We have added a recommended book title below that covers this subject.
We recommend that you purchase one of the reference books above to study for your exam. Each book is a comprehensive subject index to the NEC. They provide an even faster way to look up answers in the code and are far more detailed than the index at the end of the code book.
Ugly's References contain practical applications of the NEC such as Ohm‘s Law, series/parallel circuits, voltage drop, load calculations, motor phases, impediance, inductance and math formulas you are expected to know. “Basic Knowledge” and “Electrical Calculations” are subjects covered in the exam and are assumed (most likely not listed as a subject for electrical and mechanical exams of all types).
Sample exam questions are sourced from the National Electrical Code (NEC) and Ugly's References. A subject category index mapped to question numbers is included with the answer key.
Bookmarks have been added to help the user randomly jump to specific questions related to NEC Articles in the code.
Additional bonus sample calculations for Ohm's Law and Series/Parallel combination circuits are included.
The total number of questions in this package: 2,450
