Every school is different and I am pretty sure that now all schools cant send kids home as it is 'discriminatory' towards the child.

But in my opinion it is in the best interest of your child and the others to keep at home until its gone. If they go to school it just spreads it and then once your child has gotten rid of it they might contract it again from another child and the cuycle just goes on and on!

Mitch4now- I did the same thing with my kindy class this week as nits is going around! The kids were quite open about is as I I even explained that when I was little and at school I had nits as well as they can just jump into your hair.
