So I got my annual review and offer for next year. It looks like I'm going on my first full loop from grade 4 to 5. I have about a week to choose if I want to do the loop or stay in fifth. I'm leaning towards taking a loop class from fourth to fifth. I taught fifth this year and I had a really challenging class in terms of behaviors. I was the new teacher on staff and got all the new kids. I also got dumped on a little in terms of which kids placed in my class. I expected this going into a new school. Anyway, I hear that my class next year in the loop will be the total opposite. What are the pitfalls of looping? I've seen it in action in my school. But I want an outside view and opinions.
