@skjj52 I don’t believe years after 2015 have been released yet. The new dorms were completed a few years and should be helping retention, especially with a two year residential requirement.
Is your child leaving SMU? Where are these departing students headed? Another top 60 national University? I don’t sense that things have gotten worse. Maybe your kid is among the 9% that end of not returning and is among a group within that subset?
If you go to a small liberal arts college like Southwestern, Austin College, Rhodes, W&L, etc. you’ll get more personal attention.
