for comments since at least 2002. I worked with admissions documents in the ASB from 2002-2005 and unless I'm misremembering, unless the Bishop sent a letter along with the form, it was just the form. With regards to the Seminary recommendation, there was room for comments, but I can't recall ever seeing more than a few phrases on there, and if there was a lot of information, the teacher was just writing a defacto letter of recommendation for the individual. In three years, I can't recall ever seeing one with negative comments about the student written on it.
I wasn't involved in the process of accepting or rejecting people, but I think people place more weight on the potential of a seminary teacher to sink things than actually exists. I'm not saying that couldn't happen, but it would be a VERY rare individual that doesn't get in because of something their seminary teacher wrote.
