I have also noticed the diagnosis has increased since the school schedule took out recess every day. Kids with energy and no way to expend it during the day...
Classroom time nor is ridiculous especially for early grade schoolers. Naps are a no longer an allowed activity in most Kindergarten classes. Pre-K needs to be ended now. Grade school K-third grade should be out at 1:30. Fourth through eighth grade or sixth if a middle school should be out at 2:30. Middle /junior high and high school should be out at no later than 3:30. School years should begin Tuesday after Labor Day and end Friday before Memorial Day. Recess in grade school should be an after lunch activity and Physical Education should be a required three year twice to three times a week course in high school. Block scheduling should be ended in all public schools.
