Straight Talk About Grading @ Princeton

Shirley Tilghman:

In the spring of 2004 the faculty adopted by a two-thirds majority vote a set of simple guidelines regarding the grading of undergraduate academic work. Of all the policies I have overseen in my 10 years as president, this has been the most contentious and misunderstood among students, parents and alumni. With the policy now seven years old, I thought it might be helpful to review its original rationale and update you on its impact on grading at Princeton.

Prior to 2004 there was no policy to guide faculty in awarding grades, and over time two worrisome trends became apparent. First, the percentage of "A" grades for coursework rose over the past four decades, from 30% in the 1970s to 32.5% in the 1980s to 43% in the 1990s and 47% in 2001-04. As much as we like to claim that each new class equals or surpasses the talents of the previous class, this increase was not unique to Princeton, but was happening in many secondary schools, colleges and universities. If left unchecked, grades would soon cease to be a meaningful way to provide feedback to students about their academic progress.

More troubling to me was the fact that the rate of inflation was not uniform throughout the curriculum. As shown in the orange bars in the figure here, "A" grades awarded by departments ranged from 67% at one end of the scale to 35% at the other. The impact of this disparity was clear--students concentrating their academic work in departments at the higher end of the scale had a significant advantage over those at the lower end. This struck many of us as deeply unfair to our students.
