Limit Summary
Advanced Computing Systems & Services: Adapting to the Rapid Evolution of Science and Engineering Research 20-606 12/03/2020 1

An organization may submit only one proposal but may be a subawardee on other proposals responding to this solicitation. The restriction to no more than one submitted proposal as lead organization is to help ensure that there is appropriate organizational commitment necessary for responsible oversight, by the potential awardee organization, of a national resource.

Collaborative projects may only be submitted as a single proposal in which a single award is being requested (PAPPG Chapter II.D.3.a). The involvement of partner organizations should be supported through subawards administered by the submitting organization.

These eligibility constraints will be strictly enforced in order to treat everyone fairly and consistently. In the event that an organization exceeds this limit, the proposal received within the limit will be accepted based on the earliest date and time of proposal submission (i.e., the first proposal received will be accepted and the remainder will be returned without review). No exceptions will be made.

National Artificial Intelligence (AI) Research Institutes 20-604 12/04/2020 2

An organization may submit no more than two proposals to this solicitation as lead institution. Organizations wishing to contribute to more Institute proposals are encouraged to participate as non-lead organizations in Institute proposals in a manner that helps to create significant new research capabilities in new centers of AI leadership throughout the country. In the event that an organization exceeds these limits, proposals will be accepted based on earliest date and time of proposal submission, i.e., the first two proposals will be accepted, and the remainder will be returned without review.

  • Planning or Pilot Projects (PPP) track: An eligible institution cannot have more than two active PPP awards. A new PPP proposal can be submitted by an institution with two active PPP awards if at least one of the awards has had its final report submitted before the submission deadline for HSI proposals.

A collaborative award counts as an HSI IEP award for all institutions. For institutions with a current Track 1: Building Capacity award under the previous solicitations 18-524 and 19-540, each award is considered an IEP award for the purpose of calculating active awards for this track.

Major Research Instrumentation Program: 18-513 01/01/2021 See next
column

Three (3) as described below. Potential PIs are advised to contact their institutional office of research regarding processes used to select proposals for submission.

The MRI program requires that an MRI-eligible organization may, as a performing organization, submit or be included as a significantly funded[3] subawardee in no more than three MRI proposals. Beginning with this competition, each performing organization is now limited to a maximum of three proposals in revised “Tracks” as defined below, with no more than two submissions in Track 1 and no more than one submission in Track 2. Any MRI proposal may request support for either the acquisition or development of a research instrument. Within their submission limit, NSF strongly encourages organizations to submit proposals for innovative development projects.

Any MRI proposal may request support for either the acquisition or development of a research instrument.

  • Track 1: Track 1 MRI proposals are those that request funds from NSF greater than or equal to $100,0001 and less than $1,000,000.
  • Track 2: Track 2 MRI proposals are those that request funds from NSF greater than or equal to $1,000,000 up to and including $4,000,000.

Note: The 30% cost-sharing requirement applies to only the portion of the total project cost budgeted to non-exempt organizations, including those participating through subawards. When required, cost-sharing must be precisely 30%. Cost sharing is required for Ph.D.-granting institutions of higher education and for non-degree-granting organizations. Non-Ph.D.-granting institutions of higher education are exempt from cost-sharing and cannot provide it. National Science Board policy is that voluntary committed cost sharing is prohibited. See section V.B. for specific information on cost-sharing calculations and the solicitation text for definitions of organizational types used for the MRI program.



[3]An unfunded collaboration does not count against the submission limit. Inclusion as a funded subawardee on a development proposal at a level in excess of 20% of the total budget requested from NSF, or as a funded subawardee, when allowed, on any acquisition proposal, will be counted against an organization's proposal submission limit. Separately submitted linked collaborative proposals count against the submission limit of each of the submitting organizations. However, if a subaward to an organization in a development proposal is 20% or less of the proposal's total budget request from NSF, the subawardee's submission limit will not be affected. For subawards within a linked collaborative proposal, the 20% threshold applies to the budget request from NSF in the proposal containing the subaward(s), not to the combined budget request from NSF for the collaborative project.
