I believe that it should be left to the discretion of the practitioner under which the student is working and the client owner of the animal to be treated to decide what the student is and is not allowed to do. I think more experience under the supervision of a veterinarian will produce a more competent new graduate veterinarian which will benefit both the veterinarian and the clients. Students would perform tasks under the direct supervision of a veterinary who can step in if necessary making it an effective and safe learning environment for the student and patient.
