In October, Gordon Caplan, a Connecticut-based lawyer, was sentenced to one month in prison, a year of supervised release, 250 hours of community service, and a fine of $50,000.
Caplan pleaded guilty in April, admitting to paying Singer $75,000 to have his daughter's ACT exam answers changed.
Prosecutors asked the judge to sentence Caplan to eight months in jail, a year of supervised release, and a fine of $40,000. Caplan's lawyer had asked for a two-week sentence.
According to a criminal complaint filed in March, Singer told Caplan that he needed his daughter "to be stupid" when a psychologist evaluated her for learning disabilities in order to earn extra time for her ACT exam.

"I also need to tell [your daughter] when she gets tested, to be as, to be stupid, not to be as smart as she is," Singer said, according to court documents. "The goal is to be slow, to be not as bright, all that, so we show discrepancies."
In recorded phone conversations published in the criminal complaint, Caplan shows concern over being caught on multiple occasions.
Caplan was charged with conspiracy to commit mail fraud and honest services mail fraud.
After agreeing to plead guilty in April, Caplan released a statement in which he said he takes "full and sole responsibility" for his conduct, according to Bloomberg.
"I want to make clear that my daughter, whom I love more than anything in the world, is a high school junior and has not yet applied to college, much less been accepted by any school. She had no knowledge whatsoever about my actions, has been devastated to learn what I did and has been hurt the most by it," Caplan said.
The law firm Willkie Farr & Gallagher put Caplan on leave after his indictment. It is unclear what his current standing with the firm is.
