S.C. Code § 40-11-290
The board may grant a license or certificate to an applicant holding a license or certificate in good standing in another state whose requirements for licensure and certification are equal to or greater than those required by this chapter if the board has authorized an exam waiver agreement with the State. An applicant may exempt the technical examination required for certification if the applicant can verify passing an examination in another state which is essentially the same as the examination required by the department regardless of the absence of a reciprocal agreement with that state. An applicant for certification or licensure under this section may be required to pass the South Carolina Commercial Contractors Business, Law and Project Management examination, and must comply with all other licensing and certification requirements of this chapter.
