My sons go to private school and they gave me no pushback when I provided them the form. If you act as if you are uncertain as to whether it is acceptable, then they might give you problems. Any school that claims that they follow the state guidelines for vaccinations (which is likely the vast majority) should accept the form, since the exemption form is provided by the. That form is intended for private schools, daycares, etc. as well as public schools. I also use it for summer camps for my kids and again, haven't had a problem.
