They've been doing that at our school in PA for as long as I can remember. We get a letter informing us of our child's BMI. I have one son who is on the fat side of the BMI and another that is on the skinny side. They are two years apart and eat the exact same meals, with almost the exact same portions. Not all kids are fat because they eat whatever they want...some kids just are. The doctor tells us not to worry about it, they'll even out in a few years.

I don't have a problem with the BMI thing, but I don't need it to tell me that one of my kids is skinny and the other is fat.
