anything good come of cheating?
A 2011 analysis by The Wall Street Journal showed a bulge in New York City students’ test scores right over the passing mark. The evidence strongly suggested teachers were manipulating grades on statewide Regents Exams and helped spur changes to testing procedures.
Thomas Dee, a professor at Stanford University, updated the numbers from the initial analysis after the state took steps to eliminate grade inflation. The findings: Teachers who manipulated scores appear to have been motivated by altruism, score manipulation was eliminated by 2012, and the graduation gap between black and white students is about 5% larger in its absence.
