As part of The Race To the Top, Georgia has decided to use TKES (Teacher Keys Effectiveness System) as a means of evaluating teachers. Here is a file that explains the whole system.
Some counties have been experimenting with this - and the whole state goes live next year.
Henry County has a file that will help you create your own file to wow your evaluator. This will also help set your expectations of what evidence you will need to provide.
Some schools are requiring portfolios as a means of evaluation. Again the Henry document is a good place to start.
A teacher I know uses the Henry file as a start, and behind each standard puts examples that prove that standard has been met.
