The national accrediting agency for Career Education Corp. on Monday decided not to pursue penalties against 71 campuses that had been under review over reported problems with job placement rates. Four campuses, however, were placed on probation. The Accrediting Council for Independent Colleges and Schools had asked the for-profit higher education provider to demonstrate that its job-placement reporting was adequate after a recent review  by an outside law firm found that some campuses lacked sufficient documentation. Career Education's president and CEO, Gary E. McCullough, resigned  shortly after that news broke. Steven H. Lesnik, the new CEO, said in a news release  that the company "had made great strides" but would continue to improve student job placement results.
