Where is the Common Core for principals?

Okay…I don’t actually want Stepford principals any more than I want Stepford students. The varied personalities and abilities add flavor to any classroom. However, the EXPECTATIONS of principals are often so varied and even contradictory from one principal to the next, it can leave me wondering if I have any idea at all of how to do my job! How often do you get a new principal? How do you adapt? Should we become Stepford teachers based on each principal? Or risk a lowered evaluation if the current principal doesn’t like all the wonderful things that last year’s principal commended you for?
