S.C. Code § 59-59-110
During the 2007-08 school year, each public high school shall implement a career guidance program model or prototype as developed or approved by the State Department of Education. At least annually after that, certified school guidance counselors and career specialists, under their supervision, shall counsel students during the ninth and tenth grades to further define their career cluster goals and individual graduation plans, and before the end of the second semester of the tenth grade, tenth grade students shall have declared an area of academic focus within a cluster of study. Throughout high school, students must be provided guidance activities and career awareness programs that combine counseling on career options and experiential learning with academic planning to assist students in fulfilling their individual graduation plans. In order to maximize the number of clusters offered, a school district is to ensure that each high school within the district offers a variety of clusters. A student may transfer to a high school offering that student's career cluster if not offered by the high school in his attendance zone.
