Posting in the Denver airport using my Verizon National Access while waiting for MD to stand in the coffee line. Saw this when I read the New York Times in flight. Every now and then they get it right. Money quote:
As Jodi Kantor reported in The Times this week, B.M.I. scores and the percentile rankings can confuse already overburdened parents and demoralize students, who now have one more grade to consider. The index also isn’t a particularly precise measurement tool. Muscles, which weigh more than fat, can push up a B.M.I., labeling even a young athlete as physically unfit. If schools are going to hand out B.M.I. reports they need to do a better job explaining their significance to parents and children.
