Enjoy a short vacation, if possible. Complete or reschedule projects. September is not the month to move, sew a new wardrobe, or build a dining table. Ask a professional colleague to describe the in-service workshop in your district and help you prepare for the beginning of school. You will be inundated with welcomes, speeches, announcements, regulations, and insurance agents.
Some systems also have orientation sessions for beginning teachers.
You may have one or two half-days to organize your room, obtain books and supplies, and prepare for the opening of school. You will be given volumes of material. It is important for you to pay particular attention to your system's discipline policy and procedure. Double-check your plans and materials. Make sure you understand the process for distributing the numerous forms required on the first day of school.
