Principals will observe classrooms more often and give timely feedback. One teacher said that in the past there hasn't been much of a conversation about how teachers were doing.
The model has already been tested in a few area schools to work out problems.
Bryan Devine from the Peoria Federation of teachers said it's about time.
"You know, the teachers asked for this change a long time ago before the state mandated it because we feel that as teachers, we want our profession to be held to a high standard," Devine said.
The state mandates that it be in place by 2016, so Devine said they are way ahead of schedule. It's part of a piece of legislation called The Performance Evaluation Reform Act, which was passed in 2010.
It's supposed to guarantee that teachers and principals are evaluated by a state qualified evaluator, include student growth as a significant part of principal and teacher performance evaluations and ensure teachers get constructive feedback.
