"A USA TODAY investigation, based on documents and data secured under D.C.'s Freedom of Information Act, found that for the past three school years most of Noyes' classrooms had extraordinarily high numbers of erasures on standardized tests. The consistent pattern was that wrong answers were erased and changed to right ones....
In 2007-08, six classrooms out of the eight taking tests at Noyes were flagged by McGraw-Hill because of high wrong-to-right erasure rates. The pattern was repeated in the 2008-09 and 2009-10 school years, when 80% of Noyes classrooms were flagged by McGraw-Hill.
On the 2009 reading test, for example, seventh-graders in one Noyes classroom averaged 12.7 wrong-to-right erasures per student on answer sheets; the average for seventh-graders in all D.C. schools on that test was less than 1. The odds are better for winning the Powerball grand prize than having that many erasures by chance, according to statisticians consulted by USA TODAY.
"This is an abnormal pattern," says Thomas Haladyna, a professor emeritus at Arizona State University who has studied testing for 20 years."
