About Cosigners

What is a cosigner?

  • A cosigner accepts equal responsibility for the repayment of a Certified Private Loan together with the student borrower
  • A cosigner may be required if the credit check determines the student does not qualify for the Certified Private Loan individually
  • Even if the student qualifies for a Certified Private Loan without a cosigner, by choosing to add a cosigner, the student may receive a lower interest rate

Who can be a cosigner?

  • The cosigner must be a US citizen or permanent resident
  • The cosigner must be at least 18 years old
  • The cosigner must pass a credit check
  • The cosigner does not need to be related to the student, but many students ask a parent to cosign their applications
