The National Physical Therapy Exam (or NPTE) is the measuring stick by which all new physical therapy graduates are measured. To get into PT school, you had to overcome many course exams, and most schools require the GRE to even apply, but the NPTE is in a league of its own.
The NPTE is an exam that is designed to not just test the basic recall memory of PT students. From personal experience, I can tell you that the questions on the NPTE really stretch your skills of clinical reasoning and putting multiple subject materials into on problem. The entire exam is comprised of multiple choice questions that can trick even the most seasoned veterans.
