The grant's project period can be extended for a period of up to 12-months beyond the original expiration date as referenced in the Notice of Award as long as:

• No term of the award specifically prohibits the extension,
• No additional funds are requested, and
• The project’s originally approved scope will not change. 

Effective October 1, 2011, grantees must use the No-Cost Extension feature in the eRA Commons to notify NLM when they exercise their one-time authority to extend the final budget period of their grant. NLM will no longer accept these notifications via other means. See NOT-OD-11-098. In extending the final budget period through this process, the grantee agrees to update all required certifications and assurances, including those pertaining to human subjects and animal welfare, in accordance with applicable regulations and policies. All terms and conditions of the original award continue during the extension period.
