You have to communicate with parents. You know it. They know it. It's not always fun, but it is necessary. You communicate with them about everything, and you do it throughout the year, so it's easy to see how some things can fall through the cracks or simply be ignored by parents.
But, health information cannot be ignored. You have to have the information on the student to properly and completely fulfill your duties as caregiver of the student while they are at school. And that's exactly what we encourage you to tell parents.
We've found that when school administration and health services explain not just what they're requiring, but why they're requiring it, the collection and enforcement headaches are alleviated. During the school year, students spend a significant portion of each day in the care of school staff. That time increases dramatically when you factor in sports. And with boarding schools, the school is the primary caregiver all the time.
