Fish Gotta Swim, Teachers Gotta Cheat?

Remember the story about the cheating schoolteachers in Chicago? The theory was that high-stakes testing, by putting more pressure on students to pass, creates a stronger incentive for teachers to not leave those students behind – and that a fraction of those teachers, generally the worse ones, went so far as to cheat on behalf of their students. Looks like it may have been happening in Springfield, Mass., too.
