As part of our program we generally have a day or two a week free. At some point it was recommended that we sub, so I went through the training. The first week it took me some time to figure out how the sub calling system worked. Essentially, if you don't take the sub they offer, you're out of luck. There usually aren't enough sub jobs in the system at any one time to get one by calling in yourself. Other subs have told me that they take whatever they're offered and then cancel it if they decide it won't work for them.
This week I had my first-ever sub job. It was in the moderately handicapped special education room at a local high school. The people who work there are angels. They are dealing with a broad range of cognitive and physical disabilities (kids with only physical disabilities are in regular classrooms). These "kids" are adult-sized and can be as old as 21, so they aren't little. The kids themselves are fine, but there's a lot that has to be done for them (many need bathroom help or diapers). While I was there we even took a small field trip that ended with four very tired and cranky teenagers, which made it hard for them to control their own behavior.
I can honestly say that special education probably isn't the place for me. I'm a little sad that I'm not up for that kind of challenge. Even so, I'll probably sub there again.
