S.C. Code Ann. § 59-156-180: Professional development.

The General Assembly recognizes there is a strong relationship between the skills and preparation of prekindergarten instructors and the educational outcomes of students. To improve these educational outcomes, participating providers shall require all personnel providing instruction and classroom support to students participating in the South Carolina Child Early Reading Development and Education Program to participate annually in a minimum of fifteen hours of professional development, including, teaching children from poverty. Professional development should provide instruction in strategies and techniques to address the age-appropriate progress of prekindergarten students in developing emergent literacy skills, including, but not limited to, oral communication, knowledge of print and letters, phonemic and phonological awareness, and vocabulary and comprehension development.
