It turns out that the school district where I'm applying requires my last principal to give me a reference. I haven't worked in six years (I've been home raising my kids), and the principal where I used to teach has retired and moved out of state. I don't know where he is, or if he would even remember me after all this time. I worked in a huge school. I can use a few former co-workers, but they really need a reference from the principal. Period. So on to Plan B, which involves applying as a substitute teacher. In addition, I will send off some resumes to area private schools, in case they do not have such rigid rules. Should I address my reference situation in my cover letter? I can use former co-workers, and I have a supervisor from a job I held eons ago, but just not the most recent principal. And if I do address this in the cover letter, do you have any suggestions on how I might put a positive spin on things? Of course I'm most likely to end up doing time as a sub. Oh well, it will be good for me. I would still like to thoroughly exhaust all of my options though.
