They are quite desperate for teachers so most people will be allowed in.
The administration needs to review why they lose half their staff every year and whether this is really benefitting students and their families.
Fellow teachers are some of the hardest working, most passionate people I have ever met. You have to be to put up with the administrative incompetency and stay in this job.
They seem to be focused on an impossible idealized ideal without wanting to really listen and put in the work they need to make it a feasible reality for parents, teachers, and students.
Be prepared to work 12-16 hours a day including weekends. KIPP will required you to do many additional inane data tracking tasks and minute by minute lesson plans (50 page lesson plans... No joke) or risk public shaming and being fired.
Comparable to public school salary, benefits are worse, but you will work roughly double the hours at KIPP versus the local district (I've worked the same teaching position at both). KIPP makes you do many additional unpaid tasks on the top of your contractual obligations.
