D.C. Launches Rigorous Teacher Evaluation System - washingtonpost.com:
"Rhee is investing $4 million in the system, called IMPACT, which will also assess teachers against an elaborate new framework of requirements and guidelines that cover a range of factors, including classroom presence and how carefully they check for student understanding of the material.
But IMPACT is likely to be another flash point in Rhee's turbulent relationship with local and national teachers union leaders. They say that growth statistics are too unreliable to include in performance evaluations and that the new assessment system -- which the District can legally impose without union consent -- is an instrument to identify and remove struggling teachers, not a means to help them improve."
