The small print on ours says that all efforts will be made to contact persons listed before making that decision..

But I also would much prefer them to seek medical assistance ASAP if it were needed. If I had any doubts about their ethics on seeking medical assistance, my kids wouldn't be going there.
I would appreciate if that small print was on my form.
If i followed that philosophy, i would never let my kids out of my sight. I am not up for homeschooling, and so i do have to have a certain amount of trust in the care providers, but i'm not up for giving a blanket consent.
