do i need to go to grad school to become a physical therapist
Depending on the structure of the program, you may or may not need to complete your bachelor's degree before entering the program...especially if you apply to the doctorate level program. So, yes, one does need to go to grad school to become a PT. It would be worth your while to go to the apta website at www.apta.org and click under education to get a list of accredited PT programs. Then you can visit each school's website to get a better idea of their entrance requirements.
