Authorities said the 51-year-old paid $15,000 to rig her son’s ACT exam in 2017. She’s also accused of falsely listing her son as African American and Hispanic on college applications to increase his chances of getting admitted. Authorities have not specified her son’s race.

Klapper said the scheme’s organizers listed her son as a minority without her knowledge. Her lawyers say she regrets her involvement in the scheme.

Prosecutors had recommended four months in prison. Klapper’s lawyers countered, saying she deserves home confinement and a $20,000 fine.

Klapper’s sentencing comes a day after actress Felicity Huffman reported to federal prison in Dublin to serve a two-week sentence for her role in the scandal.

Stephen Semprevivo and Devin Sloane, who paid to get their children into prominent universities under the guise that they were recruited athletes, were each sentenced to four months in prison.

Only Menlo Park food entrepreneur Peter Jan Sartorio so far has escaped during time in jail, He was sentenced to one year of probation, complete 250 hours of community service and to pay a fine of $9,500 last week.

More than 50 people — parents, coaches, test administrators and conspirators — were charged in the scandal, in which prosecutors said Singer either facilitated cheating on standardized tests or bribed college coaches to give students an advantage in the admissions process.

Several other Bay Area families have entered guilty pleas and are awaiting sentencing including Bruce and Davina Isackson of Hillsborough.

Of those charged, more than 30 are parents, accused of conspiring with Singer. More than 10 of those parents have pleaded guilty to conspiracy to commit fraud.

Singer pleaded guilty in March to four charges related to cheating on standardized tests and bribing college coaches and administrators.
