I was particulary interested in idea that, despite the fact that principals are supposed to be instructional leaders, what often gets them into trouble is poor management skills. The most important thing an administrator can do is hire the right people for the building/classroom. I have heard that, every time you hire a teacher, you are making a millions dollar investment in this person, by the time you consider a 34 years of salary and benefits. This drives home the point that we don't have an employee to waste.
