I just got back from UT recruitment. SDT did fully participate, but they did last year as well. If everyone takes full quota, then 910 placements against 1,268 signups (from this site) and a 72% placement rate.
Not a great rate. Of course, it includes PNMs who withdrew of their own accord for their own reasons.

IMO the rate is so low because of drop out. For many girls once the big six is off their schedules, they quit. Which is a huge shame because there are some amazingly strong chapters at UT outside the Big Six, I might even go out on a limb and say even stronger chapters. But old traditions die hard and if it is better to be out of letters in order to satisfy what they think so pecking order, then so be it.
