The following words of wisdom are from a blog called Ed in the Apple. I haven't had time to read anything else by the Apple, but this one is a big, shiny McIntosh--crisp, tasty, and more than a bit tart.
Perhaps the most deeply flawed of all the Klein faux “innovations” is the policy which requires that excessed teachers are not placed in other schools but placed in a pool that replaces absent teachers on a day-to-day basis, at a cost to the system of over $100 million a year.
The theory: every single teacher entering a school must be chosen by the principal, with strong suggestions that new teachers will be more malleable and effective than senior teachers.
There is no evidence that this policy has improved student achievement, there is evidence that the policy has eroded student achievement...
The ATR pool concept is a failure, it not only does not improve student achievement there is an excellent argument that it reduces student achievement, at an enormous financial cost. The ending of the policy would place more experienced teachers in the classroom, and, free up more than $100 millions a year.
