How grades convert to points here

Duke University uses full plus/minus grading, so an A- is 3.7, a B+ is 3.3, and each modifier moves the average by 0.3 points. Over a four-year transcript the difference between consistently earning A- and consistently earning A is roughly a third of a grade point — enough to cross most honors thresholds.

Latin honors at Duke University

Duke University awards Latin honors by class rank rather than a fixed GPA. Summa: top 5% of the graduating class; magna: next 10%; cum laude: next 10% (roughly top 25% overall), calculated separately for Trinity College and the Pratt School of Engineering.

Because honors here are relative, your own GPA only tells you half the story. The other half is the distribution of the graduating class, which is why Duke University typically publishes the qualifying GPA after the fact rather than in advance.

The part students usually miss

Because the percentile bands are fixed but grades have inflated, the effective GPA needed just to qualify for any Latin honor has crept up over two decades — recently around 3.93+ for Trinity and 3.88+ for Pratt, near the ceiling of the scale.

Frequently Asked Questions

Does Duke University use plus/minus grading?
Yes. A- counts as 3.7, B+ as 3.3, and so on — each modifier shifts the value by 0.3 points.
What GPA do you need for honors at Duke University?
There is no fixed number. Summa: top 5% of the graduating class; magna: next 10%; cum laude: next 10% (roughly top 25% overall), calculated separately for Trinity College and the Pratt School of Engineering., so the qualifying GPA is determined after grades are final and moves from year to year. Historical cutoffs are the best guide available in advance, but treat them as approximate.
Can I rely on this number?
It applies Duke University's published scale to the grades you enter, so for a standard letter-graded course load it should match. It will not account for transfer credit, courses excluded from the GPA by policy, or program-specific weighting. Your registrar's figure is the official one.
