How does the Constructing, Altering or Improving Contractor (C-42) exam work?
The Constructing, Altering or Improving Contractor (C-42) license comes from the Nevada State Contractors Board. You apply to the NSCB with your experience and financial statement, the Board sends an exam eligibility letter, and you book the CMS and the trade exam with PSI. Scores come right after the exam.
- Every Nevada contractor license needs the Business and Law (CMS) exam plus a trade exam for the classification, both given by PSI.
- The CMS is open book with the Construction Business and Law Manual for Nevada; trade exams are closed book except for the code references their outline allows.
- PSI charges $95 for one exam portion, or $140 for a trade exam taken with the CMS, and you get three attempts before the application is void.
- The Board sets a bond from $1,000 to $500,000 and a monetary limit on every license, based on your experience and financial statements.
