The Accrediting Commission of Career Schools and Colleges, a national accrediting agency, has dropped an inquiry into 10 campuses owned by Career Education Corp., the for-profit higher education provider announced Tuesday. The accreditor had asked the company to "show cause" why the campuses should not have their accreditation withdrawn in the wake of Career Education's earlier acknowledgment that it lacked sufficient documentation for some job placement data. The campuses are now free to pursue new academic program approvals.
