S.C. Code Ann. § 40-49-60: Examinations for certificates.

Each such board of examiners shall designate the time and place for the examination of all persons desiring to secure a certificate as herein provided for. Each such applicant shall be compelled to pass such examination as to his qualifications as such board may direct. Such examination shall be made in whole or in part in writing, and shall be of a practical and elementary character, but sufficiently strict to test the qualifications of the applicant.
