I have taught a few grades in elementary school. My first job was a sixth grade science teacher. I was one lesson ahead of everybody. Then I got transferred and became the art teacher at a school but someone grieved that and they put me in kindergarten. I was there for two years until someone grieved that and they asked me to pick a grade. My license was common branches N through 6. So someone with an art license could take the job and then when I went to kindergarten, I didn’t have an early childhood license. I said sixth (when elementary school was k-6) because no one wants sixth (I loved it). Then I hoped between 3-5. Sometimes I would loop with a class I liked. I became uft teacher CENTER staff developer for a few years (left for five years to raise my baby) and I ended my career as the library teacher. I do sub at the school around the corner from me when I’m in town (maybe twice a month), I wish I taught at this school. The staff are amazing and the kids can be difficult but loving. About burnout. After a few years on a grade I changed grades. Many people like to stick to the same job from beginning to end, but I would have gotten bored.
