The Last Laugh: High scoring D.C. school probably cheated

When I say probably, I mean most definitely. As one statistician put it;
“The odds are better for winning the Powerball grand prize than having that many erasures by chance,”
It seems that this school which had such high gains also had high erasure marks. When the average erasure mark is less than one per test and this school has over 12 per test...yeah something's not right.

Best part, besides the praise they got, is the bonuses all the teachers and principal received.

Unfortunately, as politicians move to tie a teacher's pay and evaluations to test scores, I think we will be seeing more of these types of incidents.
