In my years of teaching, I have found this form to be the most beneficial when documenting behavior, notes, transportation changes, absences/tardies, etc.
I keep the documentation form and parent contact log on a clip board that I carry around everywhere we go. The clipboard is one that opens up and allows you to store stuff (You can find these at any office supply store). Inside, I keep a copy of my students emergency contact information, nurses passes, and office referral forms. Having the documentation form and parent contact log easily accessible with these other resources makes for a simpler time keeping up with data.
Feel free to edit it to match your personal classroom needs.
