I am aware of these problems. Of course, this creates more problems and mistrust of school staff by parents. I think we need to do a better job of training and supervising teachers. As you know, people in most professions go through internships where they have a lengthy period of supervision. Teachers are often dumped in classrooms where they must sink or swim.
Many teachers feel isolated and powerless.
Sometimes, they perceive school psychologists as living in an ivory tower. Maybe you can find a way to provide some training for these teachers this would also benefit the kids. In this case, the people who seemed to be over-diagnosing children were doctors, not teachers. Maybe this study is a good way to start the education process. Researchers examined about 30,000 grade-school children in two districts in southeastern Virginia and found that pupils took drugs for ADHD in school at two to three times the expected rate, according to the study in the American Journal of Public Health.
