Most teachers will leave after 1 to 2 years for good reason.
The administration puts on an initial friendly face. That quickly changes as it becomes more about making money for the school than about teaching children. Expect to spend more time on fundraising events than lesson plans or extracurricular activities (this goes for the students as well as the teachers). Teachers are actively encouraged by administration to shame students in front of their peers for not contributing to fundraising events. As a teacher, if you do not raise several hundred dollars in funds during your first few weeks in school for the Golf Outing, expect to be sat down by administration and asked to pay out of your own pocket. This goes for the Chocolate Drive as well.
Read your contract and have it looked over before signing. There are many aspects of it that administration will try to use against you.
The infrastructure of the school is painfully outdated. Do not expect to be able to make copies of worksheets or packets efficiently, print in color, or utilize technology in the classroom.
It's worth googling the names of members of administration to see what they have been involved with in the past.
You will not have enough time or energy to teach effectively at this school. It will be all about fundraising and playing catch up. You will not grow as an educator.
The most heartbreaking thing is how the priorities of the administration and the overwhelming teacher turnover rate disrupts the education of the students.
