S.C. Code Ann. § 59-156-190

Both public and private providers are eligible for transportation funds for the transportation of children to and from school. Nothing in this section prohibits providers from contracting with another entity to provide transportation services provided the entities adhere to the requirements of Section 56-5-195. Providers must not be responsible for transporting students attending programs outside the district lines. Parents choosing program providers located outside of their resident district shall be responsible for transportation. When transporting four-year-old child development students, providers shall make every effort to transport them with students of similar ages attending the same school. Of the amount appropriated for the program, not more than one hundred eighty-five dollars for each student may be retained by the Department of Education for the purposes of transporting four-year-old students. This amount annually must be increased by the same projected rate of inflation as determined by the Revenue and Fiscal Affairs Office for the Education Finance Act.
