Any document used to effect modifications to grants and cooperative agreements. Amendments may be issued unilaterally at the discretion of the Grant Officer. NASA policy is to make maximum use of multiple year grants to support research projects that may span several years. A Multiple Year Grant is generally selected for a period of three years in keeping with NASA's policy calling for research to be peer reviewed at least every three years. Periods approved under the Multiple Year Grants provision 1260.52, and funded at the levels specified in the provision, are not considered to be new awards.
Supplements require the submission of revised budget proposals and technical evaluations.
Since Supplements will be performed within the existing period of performance, certifications will not normally be required. Continued performance within a period specified under the Multiple Year Grants provision does not constitute a renewal. Peer review of the continuing research should be accomplished prior to selecting a research grant for renewal. Multiple Year Grant provisions may be incorporated into renewals. Since NASA grant recipients usually gain no measurable benefit from grants other than conducting research, cost sharing for research grants is not generally required.
