Operation Varsity Blues: 5 things to know about the college cheating scandal

No students were charged in the investigation

Here is what to know about the scheme:

1. Prosecutors said Singer's operation arranged for people to take college admissions exams in place of his clients' children by bribing college entrance exam administrators to help with cheating on admission tests. The charging documents also say Singer created false sports backgrounds for the students to make them appear to be eligible for admission to college as an elite athlete. Some students were recruited to colleges for sports they never played.
2. In addition to cheating on exams and lying about the athletic skills of his client's children, Singer bribed college admission officials and coaches at colleges across the country, prosecutors said.
3. Colleges Singer targeted for the scam include the University of Southern California, Wake Forest, the University of Texas, Georgetown, Yale University, Stanford University and UCLA. Prosecutors say the schools in general, were not involved with the scam, but coaches at some of these schools were part of the scheme.
4. Parents paid Singer more than $25 million through the Edge College & Career Network – a fake charity Singer created.
5. Loughlin and her husband, fashion designer Mossimo Giannulli, were charged with paying $500,000 in bribes so their two daughters would be designated as recruits for the USC crew team. Huffman allegedly paid to have someone take her child's college admission test.
