Critiquing Other Singers!

So I have been involved in a class entitled 'Performance Lab.' It is a mixture of Classical and Musical Theater singers in which they perform and get critiqued by his/her fellow classmates. I've noticed a lot of unprofessional things about this class, so let's start with the accompanist. First off, anyone can provide his/her own accompanist. Secondly, the school has provided an accompanist free of charge. "You have the right to remain singing. Anything you say will be used against you in the Court of 'Juries'. If you do not have an accompanist, the worst possible one will be provided to you." With that said, this accompanist is nothing to write home about. Well, let me take that back, he is. These students' parents need to know what they are getting for their money; UNPROFESSIONALISM! I have seen this accompanist, on several occasions, sing with the performer while the performer is performing. Also, knowledge of repertoire lacks IMMENSELY. But enough with that, let's get to the actual students. Unlike being in a production and performing for an audience, this performance class is to help the students become more of a performer, no matter what his/her level of singing is. So after the student performs, he/she is then critiqued by other amateur performers. This is where all hell breaks loose!!! First off, many terms are thrown around completely out of context. Some of them try and talk intellectually and don't know the meaning of most of the terms being used. Then, half these students perform worse than the student who has just performed. Then it's like the current performer gets bashed for doing a better job. The instructor of this class is a stickler for professionalism yada yada yada. This person allows a lot of non-professionalism which is something I don't understand. I have heard students comment on others people's physical ailments which is something that they can't control. Then, they have the nerve to NOT heed their own criticism. I would start with myself before telling someone what they should or should not be doing. So yeah, this is so not cool.
