Use this online Date Calendar to find out if your request is within the appropriate timeframe.

Grantees may authorize a one-time extension of the end date of the grant of up to 12 months if additional time beyond the established end date is required to assure adequate completion of the original scope of work within the funds already made available. This one-time extension may not be exercised merely for the purpose of using the unliquidated balances. Grantees are not authorized to extend an award that contains a zero balance. Please limit your justification to 1200 characters. *Per Sponsor guidelines, NSF will not accept justifications that exceed 1200 characters, therefore, NCE requests will not go through upon submission to the Sponsor.
