Hi,
I was too naïve to be nervous

. I've been teaching for over 10 years and I've never done it alone!!
We have a math and reading academic coach. (They meet with our grade level every week and give us tons of resources. They also come into our classroom and help with small groups. )
We have a testing strategist that keeps us on track with all the state, district, and campus testing.
Special Ed. paper work/students made me nervous, but we have excellent admin that help us out.
The best part is that you will have a grade level to help you out. In our grade level, each teacher plans for one subject and then we share the resources. The district writes our tests and lesson plans!!!!
We also eat lunch together daily and help each other keep track of everything that is due.
I teach 1st and get to have a teacher aide for our reading block (120 minutes.) --It's heaven!!!
I would you advise to dive right in!! Do your research on the district and check to see what support you will get. I'm a dual language, ESL and GT certified teacher in a very low SES school. It's tough because we are under lots of pressure to show progress.
It shows that you are going to be a great teacher because you want to give them your best.
