Kudos to Duke for collecting and making public data about the time to degree and the rates of completion in their PhD programs. I would be curious to see similar data from other campuses. It’s unclear how many schools collect such data systematically and they certainly donâ€™t make them public very often as the details are usually not very glamorous and can seem pretty discouraging. But itâ€™s important information for people to have as they prepare for their graduate school experiences. It can also help students from other campuses as they try to argue for better/longer support for their training.
