These are the people taking care of your children:

I had a full day of screening 2nd and 5th graders at one of my elementary schools yesterday. In the morning, we called a classroom and asked the teacher - a substitute - to send half of her class down to the nurse's office to begin screening. Her response: "Should I come with them?" 

Yes, and leave the other half of that 5th grade class alone in a classroom. Great idea.
