I suppose I am basing this on a situation where a student of mine struggled greatly to pass even the simpliest of test, not to mention they graduated with a certificate of completion from high school not a diploma, and they were documented mentally handicapped. Now as their instructor I did everything I could do to get the information understandable as well as extended time for tests (reasonably of course). This particular student was also a little person. Being a little person I have seen them work so I know they can DO the work. Being mentally handicapped yet being able to within reason answer certain questions about material they would need on a daily basis not so much.... not to mention the board they would have to pass had a time limit, is what I am talking about.
I believe that if I give EVERY opportunity for a student to be personally successful, this student may not be so in most medical fields.
I feel as instructors, we, if admissions does not offer realistic outcomes, are obligated to assist so that some students will not spend time and money only to be disappointed.
