Default Management

As the Director of Federal Student Aid's Cohort Default Rates Group within the Partner Eligibility and Oversight Services Unit, I welcome you to the Default Management website.

Partner Eligibility and Oversight Services (PEOS) calculates draft and official cohort default rates, which measure the ratio of students who enter repayment (denominator) during a cohort year and who later default (numerator) on those loans. PEOS disseminates draft and official rates to schools electronically and allows schools the ability to challenge/appeal/adjust the rates. This website integrates the publication of the official cohort default rates (CDR) while providing cohort default-related information, references, and resources for these rates in one location.

Guaranty agency and lender cohort default rates are also calculated and disseminated by PEOS; however, this website pertains only to school cohort default rates and associated issues including default prevention. For guaranty agency and lender CDRs refer to the Lender and Guaranty Agency Default Rates website.

From this page, you may also navigate to our eCDR Appeals application which is a web-based application that allows schools to submit Incorrect Data Challenges (IDC), Uncorrected Data Adjustment (UDA), New Data Adjustment (NDA), and Loan Servicing Appeals (LSA) during the cohort default rate appeal cycles. In the Cohort Default Rate Guide, you will find instructions on how to submit the Participation Rate Index challenge, Participation Rate Index Appeal, Erroneous Data Appeal, and/or the Economically Disadvantaged Appeal. All of these challenges and appeals are submitted via hardcopy.

I invite you to peruse the question and answer section (FAQs) in which we include our most frequently asked questions. Should you need any further information regarding school cohort default rates, contact our hotline at 202-377-4259 or email us at

In addition to cohort default rate assistance, Federal Student Aid also provides default prevention support for schools. For questions related to default prevention, contact For consolidated delinquency and default prevention resources, refer to the Default Prevention Resource Information web page.

Thank you,
