New York City School Calls girl Fat

The School District in New York City is combating Obesity.  They are doing fitness exams and sending home notes with students to let the parents know if their child is fat.  Well that all sounds good in theory.  However there seems to be a disconnect.  They told the girl pictured below she is overweight!!!! Just take one look and you know there is a problem. 

I think anyone with a brain in their head can tell this girl is not overweight.  4'1" and weighing 66 pounds is an issue?
