Policy to remove principals?

Just a reminder to myself here - I reviewed the Race to the Top guidelines and specifications. Needless to say - they are extremely detailed. Writing to this is going to be easy and hard, in that you know exactly what needs to be in the proposal and the points linked to each section (and subsection), but the key will be in integrating all of the portions of the proposal and the four assurances/priorities.

In looking at the turnaround priority, I noticed that "removing the principal" is required for each option, even transformational. This seems like it could have some unintended consequences - it's a disincentive to principals (and to districts) to start to work in a high-poverty or underperforming school that is approaching the 5 percent of schools that will be identified. Why would a principal - a good principal - even consider going to a low performing school if odds are that he/she will be fired in one or two years if the school doesn't improve?

I need to look into this a bit more and see what's really going on.
