An Arizona woman pleads guilty to running an elaborate scam that highlights what federal authorities describe as the vulnerability of online education to financial-aid fraud. The scheme embroiled Rio Salado College, home to one of America's largest online programs, in a half-million-dollar con.

A report released by the department says a project called the Distance Education Demonstration Program has shown that waiving financial-aid restrictions on distance-education providers did not lead to any problems. The rules were designed to prevent fraudulent correspondence programs from gaining access to federal student-aid money. But the report leaves out details about one instance in which an institution closed down after it took advantage of a rule waiver and was then found to be riddled with fraud.

The U.S. Education Department last week proposed new rules that would loosen a ban on incentive compensation for college recruiters and get rid of a financial-aid regulation. The proposal to eliminate the 12-hour rule follows years of debate. Distance-education providers have pushed the department and Congress to throw out the regulation, but others have cited fears that relaxing the rule would lead to fraud.
