Those who have a physical therapist degree should put what they have learned in practice. A school should be able to do whatever it takes to make sure that the child gets everything she needs, be it for medical reasons which subsequently will have an effect on her studies.
If the child needs physical therapy it has to be written into your child's IEP after they test him through their ways (school board team). They may use the script but I know with my daught just getting speech therapy they had to test her even after getting the script. She never had to have a script for physical therapy however. I guess depending on your district prodical.
