PhD Time-to-Degree/Attrition

Below are reports showing the academic outcomes for doctoral students and the length of time it took to reach these. These reports essentially follow the approach taken by Council of Graduate Schools’ PhD Completion Project. Doctoral study is considered to begin in the first academic year of enrollment in either the PhD program or its component Masters program. If a student took time off from their progress, this was not accounted for (in other words, their time away counted towards their time to degree or attrition). Time is measured in years and reported as Median and 90th percentile (when 90% of the attrition or graduation sub-populations have reached their respective outcomes).

These were developed and improved upon over several years, and more recent reports show additional data analysis. All data was retrieved from the University’s Enterprise Data Warehouse.
