There's a lot of political lip-service of late given to ridding schools of bad teachers. But be aware if you're looking to do so in Dallas. A 30-year veteran teacher was fired due in part to low ratings on the "Classroom Effectiveness Index," a value-added evaluation instrument. All of this started back in August when a handful of teachers were let go at the veteran teacher's school... Seems there's a huge difference between recommending termination and said termination actually happening...more.
