Andy,
Do you make judgements about the likelihood of success for students without disabilities, or do you let them take their chances if they meet the requirements for the program. Students with disabilities have been limited for many years because of other people's expectations. That is a big part of what the laws were meant to prevent. Being realistic about what the field is all about is always appropriate. Deciding FOR a student that the field is not for him/her is overstepping.
