S.C. Code Ann. § 59-63-237: Expulsion of student determined to have threatened violence with a weapon.

(A) The district board of trustees must expel for no more than one academic year a student who is determined to have knowingly and wilfully delivered or conveyed a threat to commit bodily harm by means of a weapon against students or employees of a school by means of any letter or paper, writing, document, electronic communication, or other type of communication that is intended to reach another person. The expulsion period is subject to modification on a case-by-case basis as determined by the district board of trustees or district superintendent of education.

(B) In order for a student to be expelled under this section, the board or any authority the board designates to conduct an expulsion hearing, must find, at a minimum:

(1) the threat was directed at specific students, staff, or school;

(2) an ordinary person reviewing the threat would have a reasonable expectation of a violent act resulting in bodily harm;

(3) the student making the threat could be reasonably expected to have the capacity to carry out the threat; and

(4) the threat resulted in a material and substantial disruption to school operations including, but not limited to, the cancellation of classes or families declining to send students to school in response to the threat or a lock-down of the school and students.

(C) The expulsion hearing must follow the procedures established pursuant to Section 59-63-240. Students expelled pursuant to this section must be afforded access to educational services through an alternative or virtual setting. Each local board of trustees is to establish a policy which requires the student to be referred to the local county office of the Department of Juvenile Justice or its representative.
