WASHINGTON, DC (WUSA) -- Acting DC School Chancellor Kaya Henderson says there was no cheating on the student standardized tests that were given at Noyes Elementary and seven other city schools.
Henderson says an outside security firm, Caveon, LLC of Philadelphia conducted an investigation after test scores for a total of eight schools came back with an unusually high number of erasures. Wrong answers had been erased with the correct answers then written in their places.
A statistical report in USA Today found the erasures to be highly unlikely for students.
Washington Teachers Union President Nathan Saunders says a WTU investigation concluded there was cheating, not by students or teachers, but school Principals and other test administrators.
Saunders says the motivation was bonuses paid out by then Chancellor Michelle Rhee.
Acting Chancellor Henderson says Caveon found no impropriety and "cheating iis not who we are."
Rhee has been unavailable for comment.
