Per the 1998 Amendments to the Higher Education Act of 1965, Cohort Calculation has been redefined to:

A school may exclude a borrower from Cohort default if, after entering default (240 days delinquent for monthly and 270 days delinquent for quarterly borrowers), they do any of the following:

1. Voluntarily make six consecutive payments
2. Voluntarily make all payments currently due (bring the loan current)
3. Pay loan in full
4. Receive a deferment or forbearance which precedes the default date (240 days - monthly or 270 days - quarterly).
