Document who is picking up your students each day for security and your own peace-of-mind. It can be easy to forget who just picked up Johnny when Grandma arrives to collect him!
I've actually even had to submit my logs as evidence in a custody battle, so you never know when your documentation will make all the difference! In my case, it greatly affected the welfare of one of my students.
Included are color version (background modified from design by Kira Ko) and a b/w version. Modify with your class roster and name.
