I graduated from college in May 2009 and finally got a job as a Substitute in a large district. I was told I'll start after Winter Break. My question is how do I get letters of recommendations as a Sub? My letters of recommendations are from when I student taught...I think it'll be too old to use when I apply for Teacher jobs starting this spring/summer. Do I introduce myself to the Principal/Assistant Principal and ask them to observe me teach? I've already gone 7 months being unemployed, I really want to use subbing as a way to get my foot into the door and hopefully land a full-time job. Any advice would be greatly appreciated!
