S.C. Code § 59-18-360
Beginning with the 2010 assessment administration, the Department of Education is directed to provide assessment results annually on individual students and schools by August first, except when assessments are being updated and new achievement standards are being set, in a manner and format that is easily understood by parents and the public. In addition, the school assessment results must be presented in a format easily understood by the faculty and in a manner that is useful for curriculum review and instructional improvement. The department is to provide longitudinally matched student data from the standards-based assessments and include information on the performance of subgroups of students within the school. The department must work with the Division of Accountability in developing the formats of the assessment results. Schools and districts are responsible for disseminating this information to parents.
