It is pretty amazing. While teachers are trained and good teachers do well with the teaching part, there isn't much training in behavior management and dealing with that aspect. And some children act out behaviorally when it is not an academic fit. Especially when they are younger and not able of comfortable verbalizing their feelings. Soo...teachers see behaviors as top priority and not academic needs. Which causes the behaviors to continue because teacher gets exhausted putting out fires and doesn't spend time trying to meet academic needs. It is understandable, but frustrating as a parent. My DS5 had on preschool setting that was awful. They were describing behaviors we had never seen at home. It was a very unstructure play based preschool setting and there were way too many kids and no behavior system because they thought since kids were all playing there would be no behaviors. He didn't last there long. Then in a montessori setting they didn't see those behaviors, so it was clearly just not a match as nothing else had changed.
