I'm relocating to another state and I was surprised to find out that you only need a high school diploma and to be 18 yrs. old to substitute teach (besides getting the substitute certification). This is definitely not the case in my current state - you need 60 credits here. I really don't like the idea of a fresh out of high school student teaching my class while I'm absent,but I'll have to get over that. Hopefully, I can find a good sub and request him/her when I'm out. The only pro is that I will have three assistants (self-contained room) so I'm sure they would help her/him anyway. What are the requirements to be a substitute in your state?
