It used to be that in the first few grades, there was only "S"-satisfactory, or "U"-unsatisfactory for the exact purpose of non-labeling, better self esteem. Everyone on the planet needs improvement in some areas.
   The biggest factor, is that many parents are too wrapped up in their own troubles to deal with the kids, & confuse parenting with schoolin'-do little or nothing at home & expect the school to deal with the kids. Thus, TV shows like Nanny 911 & such, "Jay walking" with Jay Letterman & such. It all starts in the cradle!
