The full effect of the plus/minus grading system on students' GPAs remains unknown a year after its implementation, university officials said.
Nowell Donovan, provost and vice chancellor for academic affairs, said the number of teachers who use the plus/minus system is unknown. He said the system was originally implemented by faculty to create a grading system that was more fair. He said he expects most professors will move to the plus/minus system within two or three years.
Donovan said higher quality universities tend to have a plus/minus system.
