Here is a good way to ruin the lives of very small children.

Give them lots of tests. Start when they are very young, say, five, in kindergarten.

Instead of letting them play or giving them age -appropriate instruction, test them.

In Chicago, the little ones will be tested again and again. By the reckoning in this article, as much as one-third of the year will be devoted to tests.

This will encourage their parents to find a charter school or leave for the suburbs.

It will dishearten their teachers, who might leave before her salary gets too high.

And it will teach the little ones to sit silently, training them for…sitting silently.
