Business and Law (CMS) and licensing help
Every Nevada contractor license needs the open-book Business and Law exam, also called the CMS. This group has the CMS books and courses, plus help with the NSCB application and the LLC or corporation.
Journeyman plumber cards
Journeyman plumber cards are issued locally in Nevada, not by the Contractors Board. These packages cover the plumbing code exams.
Code books, courses and national exams
Code courses, OSHA and NEC review, the NASCLA electrical exams and the Clark County structural welding special inspector exam.

What do people ask before buying?
Which Nevada license do I need?
The right license depends on the work. Building contractors hold a B, B-2, B-6 or B-7; engineering work such as grading, pipelines and pools is Class A; each trade has a C classification, from C-1 plumbing to C-42. Electricians also carry a local ID card.
What exams does a Nevada contractor take?
Two, both at PSI: the Business and Law exam, called the CMS, which every applicant takes, and the trade exam for your classification. The Board can waive the trade exam in some cases, for example licensure by endorsement.
Are the Nevada exams open book?
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 PSI outline allows. ICC electrician exams are open book with the NEC.
What do the exams cost?
PSI charges $95 for one exam portion, or $140 for a trade exam taken with the CMS. The NSCB application fee is $300, and your bond and monetary limit are set by the Board.
What is the new B-7 Restricted License?
A license created by SB 130 for residential remodeling jobs up to $7,000, labor and materials included. It needs no trade exam, lasts 2 years and excludes life-safety trades. The NSCB began taking applications in March 2026.
Are these the real exam questions?
No. Licensing exam questions are confidential. The courses and practice exams here are original material written to the same subjects and format, with explanations.
Does buying a package register me for the exam?
No. The NSCB approves your application and sends an eligibility letter, then you book with PSI. Electrician card candidates book the ICC exam. A package gets you ready for the test itself.
How do orders arrive?
Books ship from our fulfillment center, 1 Exam Prep; online courses and practice exams arrive by email after purchase. Rental books go back after your exam.
