A Breakdown of Cuomo's Teacher Ratings

The Huffington Post (in an article found here) breaks down how teachers will be rated under Gov. Cuomo's plan:

50% of a teacher's rating would be based on state test scores, 35% of a teacher's rating would be based on the findings of an outside "independent observer" who will conduct a one time visit to the classroom.  This means, a total of 85% of our evaluations would be removed from the hands of our community and placed in the hands of the state.

85% of teacher evaluations is in the hands of the state, and that 85% determines what teachers stay, what teachers leave, and what teachers are labeled "ineffective."
