Veteran journalist Sol Stern looks at the Atlanta cheating scandal from a different angle.

Pay for performance plans send big bucks to certain adults, he points out.

And those plans lead some people to cheat.

It is up to the people in charge to investigate.

He shows how in one egregious example in New York City, where the scores zoomed up, then collapsed, the city didn’t even bother to investigate the principal in charge of the school. She retired with a tidy boost to her pension. The city investigators said they couldn’t interview her because they couldn’t find her. Case closed.

A reporter did find her, however, at her listed address.

When the people in charge don’t want to know, they don’t find any smoke or fire or smoking guns.
