If we hold schools to the ridiculous standards of NCLB, then schools will either "fail" or learn how to cheat. The easiest way to game the system is to treat students in the at-risk groups tracked by NCLB like hot potatoes. If you can push enough of them out of your school (below the magic threshold of 11 students), they become someone else's problem. This gives school districts incentive to ghettoize at-risk kids in certain
Is a school that pushes out kids who might score low or who belong to small groups tracked by NCLB "growth targets" truly a public school?
