Colorado Technical University improperly awarded financial aid dollars to dozens of students, the U.S. Education Department's inspector general said in an audit [1] this month. The audit, whose findings were challenged by the for-profit college, a unit of Career Education Corp., recommended that the university be required to reimburse the government for $173,000 in improper payments and to examine the records of thousands of other students in its CTU Online unit to see if similar improprieties occurred.
