Drake University is considering adding pluses and minuses to grades.

The policy change has drawn opposition from many of the university’s 5,400 students but would put the Des Moines institution in step with other colleges.

The Des Moines Register reports that the current system bars such grades as D-minus or A-plus.

Drake’s faculty is expected to vote in the spring on the proposal.

Faculty members generally back the idea. The students opposed to it fear the change could harm their grade-point averages.
