At least six South Carolina school districts will be required to adopt new grading policies for the 2026-27 school year after the state passed a law banning “grading floors.” Grading-floor policies require teachers to assign students a minimum grade for assignments or grading periods—typically 50%. In some other districts, individual schools had adopted nonzero grading policies, the report found. South Carolina is not the first state to weigh in on minimum grade policies. In 2009, the Texas legislature passed a “truth in grading” law that prohibits districts from requiring teachers to set minimum grades for assignments.
