I created this document for my students' BEE folder to keep parents informed of behavior. This is based on the 6 color chart -- Purple, Blue, Green, Yellow, Orange and Red. I include the behavior categories from our report card. However, I am giving you the Word file so that you can edit the categories as needed (if formatting is off for you, let me know and I can send you a pdf of the same file). This is a form I've been tweaking for the last several years and I've found that this is a very efficient way of communicating specifics without taking a lot of time out of your day to do so.
What I did with this was went through the yearly calendar and made enough pages to fill in all the dates for the year. This way you can create ONE set of copies for the year, and pull pages as you like for filing. Or you could leave them all in your students' folder all year so you and the parent can see at a glance the progress over time.
