Examination Information

All entities applying for licensure must designate a primary qualifying party (PQP) who is employed full-time with the licensure applicant in a responsible management position. The PQP must pass any required technical examination and be able to document two (2) years of experience within the last 5 years for the classification(s) or subclassification(s) of work in which they are applying.

How to Schedule an Exam

Prior to application submission:

The qualifying party or primary qualifying party must take the required exam(s) for the license they wish to obtain. Some classifications may not require a technical exam, however, all must take the Business Management & Law for Commercial Contractor’s exam prior to application submission.

The easiest way to register to take an exam is through PSI's website, www.psiexams.com and look for South Carolina information. If an applicant experiences difficulty in reaching PSI on the telephone due to call volume, the best time to call is between 5:00 p.m. and 8:00 p.m. EST.

All study materials are provided by the testing provider, PSI, on page three (3) the PSI Candidate Information Bulletin. Contact PSI at 855-746-8173 or visit the website: psiexams.com.

There are two (2) national exams that we offer for those desiring to become licensed in multiple states/jurisdictions: the National Commercial Building Contractor exam, and the NASCLA Accredited Trade Examination for Electrical Contractors. See the NASCLA Accredited Examination Program for more information.
