چکیده (انگلیسی):

In recent years, an increasing number of colleges and universitie s have been turning away from
traditional letter grading systems that limit student grades to A, B, C, D, and F based on the
presumption that grading systems with more flexibility are advantageous to both teachers and
students. However, as with any rating system, before opting for a new grading system it is
important to recognize that modifications may result in some, possibly unintended, consequences
as well. In this paper, we discuss theoretical effects that including plus and/or minus grades may
have on Grade Point Average (GPA) and analyze data from a School that implemented such a
change.
