Most careers in physical therapy, and health care in general, require you to earn a college degree. You can start as an aide with only a high school diploma or GED certificate, but becoming an assistant requires a bachelor’s degree and becoming a physical therapist requires both and a graduate degree. Each position also requires state licensure, which involves a national exam and additional requirements that vary based on locality. Physical therapists usually find employment in a private office, patient home, nursing home, or hospital setting.
