I've found that using a rubric titled "Attitude and Behavior With A Substitute Teacher" has worked well for my students, subs, and for me.
I've just posted it, along with a few additional details on how I use it, on my blog

Thanks for sharing your substitute rubric Larry. Great idea getting the students involved in reflecting on their own behavior. I'm always curious when I get back from being out how things went, and particularly how my students behaved. I'm definitely going to try this with my "problem classes" next time I'm out.

Alice, one thing I've done that doesn't help subs is not leaving an exact seating chart. I try not to do that very often! I remember when I was a sub I hated not having a seating chart.

I spent 3 years subbing before and during the time I got my credential. There is a special circle of purgatory for teacher who don't have an up to date seating chart. I had one class that was in a funky pod-based library with no chart. I finally had the kid open up their clamshell desks and looked at the books an papers to figure out where they belonged. Needless to say, many were not in their assigned desks.
