For most grant programs, the COPS Office mails an Extension Request Worksheet to grantee departments during the last quarter of the grant period. Grantees may also submit grant extension requests in writing on department letterhead, although requests should not be submitted until the final quarter of the grant period (three months before the grant's scheduled end date). The letter should include the grant program, grant number, and the requested revised end date and/or the amount of additional time requested. The request must also be signed by the law enforcement or government executive. A justification of the extension request should be included with requests for extension periods of 18 months or longer, and must be approved in writing by the COPS Office. Please note that extensions provide additional time to complete a grant, but do not provide additional funding.
