I have a desk in my music classroom for any adults who come with my classes because I want everyone to have a home base. In September, I tape this letter to the desk. It outlines how my classroom runs and my expectations for them as well as opening the door to discussion. Unfortunately there is not enough time to meet with my wonderful aides regularly, so I've had to find creative ways to communicate with them about my needs. This seemed to work great to kick the year off, and so many colleagues have requested a copy that I wanted to make it publicly available. Feel free to borrow the parts that work for you or to completely re-write it to meet your needs. I hope it helps!
