No Child Left Behind

When you hear this, what picture comes to your mind?

I see a pack of kids enthusiastically following the leader with a goal to scale the peak, no matter what it takes, before sunset. There are few kids struggling in the back and the leader of the pack keeps pushing them and motivates them to make sure that the peak is scaled before sunset or even before.

OK, that is dreaming. The reality is that when the kids in the back start struggling and whine and make noise, the leader commands to everyone to slow down. Slow enough that everyone can walk together - even if the peak is scaled next day, it is OK as long as statistically all of them suceeded. That will account for 100 % success rate. Not bad. That, Ladies and Gentlemen is No Child Left Behind act.
