Having worked with doctors fresh out of school I think allowing them more time for hands on experience is key. As far as I read into it owners are informed and must sign off before a student vet can do anything to there animal, and that's fine. I also support a supervising veterinarian being avialable to monitor and provide help if needed.

They get so little experience in school as it that it would be real benefit to veterinarians and clinics everywhere if new "green" doctors had a bit more expirence under their belts.
