The SCHEV Web site has cohort graduation rates for first-time, full-time freshmen in our four-year institutions. Because the data include the six-year rate, the most recent report is for the cohort that entered in 2012-13.
The numbers in the green bars are the 4-year rates; those outside the end, the 6-year. You’re on your own for the five-year rates.
Notice JMU and University of Richkids approaching the W&M/UVa rates and notice especially W&L leading the pack.
If we calculate the ratio of the 4-year to 6-year graduation rates, we get:
The lower average rate for the public schools reflects the relatively larger 5- and 6-year rates at the urban schools, the former teachers’ colleges, and Tech.
