Loughlin and Giannulli said in court documents filed April 15 they are waiving their right to appear in court for an arraignment and plead not guilty, reported the Associated Press wire agency.
Both were indicted on March 12 on one count each of conspiracy to commit fraud and honest services mail fraud.
They were among 33 parents charged in the scheme, which involved bribing nonprofit head William "Rick" Singer to get their children designated as athletic recruits in order to get them into elite colleges such as the University of Southern California (USC) and Georgetown University.
Loughlin and Giannulli paid Singer $500,000 to get their daughters, 19-year-old Olivia Jade and 20-year-old Isabella, into USC as crew recruits, according to emails and phone calls obtained by the FBI.


Singer pleaded guilty to racketeering and conspiracy charges on March 12. Prosecutors said he cooperated with law enforcement for months and some phone calls he made to parents were recorded and submitted as part of the evidence against the parents.
Singer also took money from parents and arranged for associates to doctor SAT and ACT exams for children seeking to get into college. Loughlin and Giannulli weren't involved in that part of the scheme, according to prosecutors.
Loughlin, famous for her role as "Aunt Becky" on the beloved "Full House" show, and her fashion designer husband have remained silent publicly regarding the allegations.
Experts suggested that the parents' refusal to agree to a plea deal led to the second charge, which was used to pressure some of the parents into pleading guilty.
Each count carries a maximum prison sentence of 20 years along with fines that can reach into the millions.
