Internship, which involves practical experience in a clinical environment with real patients, gives you valuable insight into the diagnostic processes, assessment methods and other important variables. The internship also helps you evaluate your own personality before entering the field in a professional capacity. In the course of this internship, you learn how to apply abstract classroom theories in real-life situations. Your internship experience adds substantial weight to your CV as hands-on professional experience alone demonstrates your skills and helps you get a good job.
