@dstark - I do not have solid numbers for you. However, I did look at the “How colleges resolve sexual assault cases” link from the Washington Post that you posted. If you just look at the schools that roughly match the profile that I’m familiar with & assume it’s full year data, it doesn’t look to me like there are any more expulsions or suspensions than there were in the “old days” (BTW - MIT is definitely the outlier in this group). Honestly, there seems like there were even fewer in 2012-13 than before, but this is rough data and it might be 6 month data too.
However, there is one big caveat I should highlight. Many of the guys who might have been suspended or expelled instead ended up withdrawing from school before disciplinary hearings were held - this made it easier for them to transfer to another school, but not everyone could do this. I don’t know if that’s still the case or if they’re counted in the statistics you posted (I’m assuming not).
If you believe this, it seems like we have more cases now but no more expulsions / suspensions than before.
DCL was issued in April 2011, but iirc schools sort of knew it was coming beforehand. Several were doing their own work to overhaul their handling of sexual assault cases, but I think everything ground to a halt as they were waiting for DCL to be issued. I would say the 2012-13 school year would show only some of DCL’s effect. My guess is that 2014-15 might be the first “full effect” year.
I only occasionally talk to people in this field now (this definitely wasn’t my area of expertise; there were people including a few women’s rights activists who focused on this area). The conversations revolved around the challenges of implementing DCL, all the uncertainty it caused, and the problems it created for them in trying to do their jobs in a way they felt was fair. I did get the impression that there were more cases now. I did not get the impression they were expelling students at a higher rate. I also have the impression that things are now settling down to a “new normal”, But all this is just a guess.
