A high percentage of teachers quit every year. The high expectations, the amount of hours put in, the low pay, being at a high poverty school.... However, there is hope. A researcher, Ingersoll, suggests that working with a mentor as well as a supportive administration increases retention.
Acclaimed for being effective, this classroom management book provides much needed knowledge for teachers, old and new alike. This book will explain how to set the foundation for a well managed classroom as well as maintain it throughout the year.
Dealing with parents can be very stressful for new teachers. Keeping them involved diplomatically is key. I reccomend keeping a log of interactions with them as well as noting the students' discipline or actions if possible. These don't have to be detailed for every student, but simply something like noting that a student was being mouthy or sleeping during class can help later when dealing with parents and administrators.
Having a mentor is very important. The ability to go to someone for help in a new school, especially as a new teacher, helps with your sanity. It also gives you a sounding board for any problems and complaints you may have.
