Good question. I'm not sure what your school districts policy is, but you may want to push the issue a little bit. If you are not getting any where with your son's school, try contacting the district offices. Check out the district's website and see if there is a department called Offices of Prevention, or Health and Well-being. If you still are hitting a road block, try contacting your school board representative. As a last resort, you may want to contact a lawyer to see what your rights are.
