If you've ever had to leave a substitute teacher in charge of your room and felt like you didn't quite have everything they needed to know, this should help you solve that issue. This template also includes a minute by minute of their day on the first page, along with two subsequent pages of notes to be left about how the class was.
I also thank them for their help and to let me know what their email address is so that I can have students that misbehave write apology letters to send to them as well as if I'm able to provide them support while they're subbing on campus any other day when I'm at school. This is especially important if you are in a school like mine that has a difficult time finding subs to cover classes.
I left all my information filled in for a solid example of what I typically put if I do happen to be out for a day.
