There is currently no NSF salary cap. Current NSF 1030 budget forms have a specific place to dollar-quantify such cost sharing. The contribution, therefore, should be explained in the budget justification section and entered in Box M. on the NSF 1030 Budget Form. Because most such faculty will have different effort levels during the CY, AY and Summer, effort is recorded in three separate categories on the NSF budget 1030 Form. Because this effort level is both quite small and not to be charged to the sponsor, there are several options to present the contribution.
Some units fix the dollar amount then back into the effort percent figure.
Note that there are different rates for candidates and pre candidates. Please check on the prevailing practices of the anticipated GSRA's unit. The actual tuition requested from NSF should be indicated in the budget justification section along with any corresponding tuition cost sharing. The unit's contribution of a portion of the GSRA tuition in the College of Engineering can be shown in several ways. For funding competitions where cost sharing is not a requirement, DRDA recommends the latter, less explicit method.
