yes most definitely the curriculum should educate the student regarding professional communication. But, ideally the practice of it is on clinical placement whereby Clinical Facilitators are the one to observe the behaviour and also model the behaviour.
As program director, I must strive to model the behavior that I expect to develop within my students. Therefore, I have certain communication components that are incorporated within the curriculum to emphasize the importance of proper professional and ethical communication and behavior. My evaluation tools not only evaluate the clinical competencies of the students, but also their ethical and professionalism as it develops throughout the months of study. I have added another tool in which the student evaluates their clinical instructor on the same set of professional criteria, in order for oversight of proper instruction to occur. That has been most effective, since the clinical staff knows that they are being evaluated as well, which has really raised the bar on ethical and professional expectations. I hope this helps!
