In reading, the good teacher classes actually registered small increases in the retest, and the randomly selected group had a slight decline. On the closely monitored retest, the classrooms that the algorithm identified as likely cases of cheating had score declines of more than a full grade equivalent. The third was a randomly chosen control group. The second, the "good teachers," had large test score gains but normal answer patterns. The first, and largest, consisted of classrooms that the algorithm identified as having unusual test score gains and highly suspicious answer patterns. The 117 classrooms chosen for retesting fell into three groups. In Spring 2002, the Chicago Public Schools invited Jacob and Levitt to identify classrooms suspected of cheating so that they could be included in its regular quality control retest program. The authors' cheating algorithm relies on the fact that students in cheating classrooms will likely "experience unusually large test score gains in the year of the cheating, followed by unusually small gains or even declines in the following year." Just as important, answers within a cheating classroom will also display unusual patterns, such as identical blocks of answers for many students, or cases in which students answer difficult questions correctly but get easier ones wrong. ![]() The authors conclude that school accountability programs based on testing would be well advised to institute safeguards against teacher cheating. Their results suggest that such cheating occurred in 3-5 percent of the elementary classrooms in their sample, and that relatively small changes in incentives affect the amount of cheating. 9414), co-authors Brian Jacob and Steven Levitt use Iowa Test scores from 3rd through 7th grade students in the Chicago public schools to develop and test a statistical technique for identifying likely cases of teachers or administrators who cheat by systematically altering student test forms. 9413) and Catching Cheating Teachers: The Results of an Unusual Experiment in Implementing Theory ( NBER Working Paper No. In Rotten Apples: An Investigation of the Prevalence and Predictors of Teacher Cheating ( NBER Working Paper No. Such high stakes give teachers and other school officials a growing incentive to cheat on school accountability tests. In other states, years of abysmal test results have resulted in entire school staffs being required to reapply for their jobs. In California, teachers in schools with large increases in test scores may be eligible for merit pay increases of as much as $25,000. For teachers and administrators, the stakes are high. In the last decade, the states and the federal government have begun using student scores on assessment tests to evaluate public school performance.
