The Beaufort County school board voted Tuesday to postpone a decision on the use of grade floors until July.
An ad hoc committee of the school board has been reviewing grade floor policies and gathering feedback from parents, residents, teachers and principals.
The committee will continue to gather information on the practice and review the subject with newly appointed superintendent Jeffrey Moss before making a decision for next school year.
Moss, in an email to a board member, said there could be a place for grade floors for struggling students, but did not seem to favor their use. He said there must be consistent application of such a policy across the district.
The practice is used in some or all courses at about a dozen schools in the district.
"I think we should engage students and keep them actively involved during class and there would not be a need for grade floors," Moss wrote.
The grading practice, which some say gives struggling students a chance to recover, essentially gives them a higher "F" on a report card. If, for example, a student earns a 45 percent during a quarter, it would show up as a 60 percent. The higher grade prevents the student from falling too far behind and allows another chance to pass before semester grades are issued, principals have said.
Others call it grade inflation and social promotion.
The practice came under scrutiny after the February 2012 resignation of Beaufort High School principal Dan Durbin, who changed grades for 33 students without following district protocol.
District officials, though, have said the grade floors are different from Durbin's "unilateral" actions.
