I recently finished my credential coursework and I'm about to start subbing. I'm all cleared to work in one district, and I plan to apply to another one as well. That being said, I'm terrified. I actually have subbed about 4 or 5 times in the past, while student teaching, and also when I held a paraprofessional position, and they actually went just fine. However, I have never arrived at the start of the day to a completely unfamiliar school site to sub. What are the absolutely essential things that I should know before I start? What do you wish you had been told when you started subbing, but nobody did? I'm actually especially worried about how to handle attendance at the start of the day, as I don't know how to do this, and I imagine it might even vary from site to site. Do I have to send a kid back to the office with something? I've also been having a tough time finding positions. I emailed some contacts that I've made and gave them my ID number, and now I'm waiting. When I wake up at 5 in the morning, I receive no phone call, and when I look at their online system, there are no postings. This despite being in a very large school district that reportedly has a dire need for subs.
