Types

Research proposals may be solicited, meaning that they are submitted in response to a request with specified requirements, such as a request for proposal, or they may be unsolicited, meaning they are submitted without prior request. Other types of proposals include "preproposals", where a letter of intent or brief abstract is submitted for review prior to submission of a full proposal; continuation proposals, which re-iterate an original proposal and its funding requirements in order to ensure continued funding; and renewal proposals, which seek continued sponsorship of a project which would otherwise be terminated.
