A Memphis , Tennessee , man faces a 45-count indictment after prosecutors say he took money from teachers who paid to have other people take their certification exams . Clarence Mumford , 58 , allegedly made tens of thousands of dollars from the scheme , which operated between 1995-2010 and involved teachers and aspiring teachers in Tennessee , Arkansas and Mississippi . `` Mumford 's conduct has done harm to the systems in which unqualified teachers have been able to teach , to the individual schools , to qualified individuals who could have obtained jobs filled by unqualified teachers , and , ultimately , to a generation of our schoolchildren , '' said Edward L. Stanton III , U.S. Attorney for the Western District of Tennessee . It was not immediately clear whether Mumford has retained representation . According to the indictment , dated Monday , Mumford charged teachers between $ 1,500- $ 3,000 per exam . As part of the scheme , he allegedly collected teachers ' IDs and made fake driver 's licenses . The purported scam involved approximately 70 teachers , according to Kristin Helm , spokeswoman at the Tennessee Bureau of Investigations . None were mentioned by name in the indictment . The tests , which are required to obtain licenses , were written and administered under the auspices of Educational Testing Services , or ETS . The organization commented on the case in a statement Tuesday . `` ETS 's Office of Testing Integrity brought this case to the attention of local authorities and has worked cooperatively with them to bring the alleged perpetrators to justice . Test security and score validity are paramount to ETS , its clients , and test takers . We are continuing to cooperate with authorities and remain committed to providing fair and valid assessments . Due to the ongoing nature of this case we can not provide further details , '' it said .
