Can you have an degree in a applied science and be physical therapist assistant?

No, you cannot have a degree in applied science and be a physical therapist assistant (PTA). While some PTA programs might be housed within a college's "Applied Science" department or school, the degree itself is typically an Associate's Degree in Physical Therapist Assisting (AS PTA) or a similar, specific title. It's not a general "Applied Science" degree. The curriculum is focused entirely on the skills and knowledge needed to be a PTA.
