Felicity Huffman has agreed to plead guilty at the American University confession case.
The actress, best known for her role in Desperate Housewives, was accused of paying $ 15,000 (£ 11,500) to an invigilator to increase her daughter's SAT score.
According to Huffman, documents from the court were submitted in March paid the money disguised as a charitable donation.
Huffman said in a statement that she accepted responsibility and that she "will accept the consequences arising from those actions."
According to court records, a witness met Huffman and husband William H Macy at their home in Los Angeles.
He explained that he was checking a & # 39; test center & # 39; and could cause their daughter's answers to be changed.
Macy was not charged, but authorities did not say why.
The couple, Sofia, is an aspiring actress who goes to Los Angeles High School of the Arts.
Huffman said: "My daughter knew absolutely nothing about my actions, and in my misguided and profoundly wrong way, I betrayed her.
"This violation against her and the public I will bear for the rest of my life.
"My desire to help my daughter is not an excuse for breaking the law or being unfair."
Huffman was one of 50 people, including 33 parents, who were charged in America & # 39; s largest university entrance exams, where rich parents reportedly bribed school coaches and tested center insiders to get their children to elite universities , including Stanford and Yale.
Federal prosecutors said 13 others had agreed to be guilty.
Among them is Michael Center, former men's tennis coach at the University of Texas at Austin.
Center was accused of accepting nearly $ 100,000 (£ 76,000) to help an applicant make the transition to college.
But the applicant did not play tennis and did not even start once she was enrolled at university.
Also plead guilty are California marketing executive Jane Buckingham; Gregory Abbott, the founder of a New York food and beverage packaging company; and Agustin Huneeus, who owned a California wine company.
Two parents – Gordon Caplan, former co-president of law firm Willkie Farr & Gallagher and Peter Sartorio, packaged food entrepreneur, said they had concluded plea agreements last week.
Other parents who have agreed to plead guilty are Bruce Isackson, the president of a real estate development company in California, and his wife, Davina Isackson.
Actress Lori Loughlin and her fashion designer, husband Mossimo Giannulli, have also been charged, but they are not the ones who have agreed to be guilty.
No students were charged while the authorities said that in many cases the teenagers did not know what was going on.
