National Science Foundation - Where Discoveries Begin

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.

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.

An organization may serve as the lead institution on only one HDR Central proposal.

• 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. Institutions with an active HSI Track 1: Building Capacity award under the previous solicitations 18-524 and 19-540 are not eligible to submit PPP proposals or receive a PPP award until the prior HSI award’s final report is submitted.
• Implementation and Evaluation Projects (IEP) track: An eligible institution cannot have more than two active IEP awards. A new IEP proposal can be submitted by an institution with two active IEP awards if at least one of the awards has had its final report submitted prior to the HSI proposal submission deadline. 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.
• Institutional Transformation Projects (ITP) track: One submission per institution is allowed. Previous ITP awardees are not eligible to submit a proposal in the ITP track.

An eligible organization may participate in two Innovations in Graduate Education proposals per competition.  Participation includes serving as a lead organization on a non-collaborative proposal or as a lead organization, non-lead organization, or subawardee on a collaborative proposal.  Organizations participating solely as evaluators on projects are excluded from this limitation.  Proposals that exceed the institutional eligibility limit (beyond the first two submissions based on timestamp) will be returned without review regardless of the institution's role (lead, non-lead, subawardee) in the returned proposal.

Alliances: Only one proposal may be submitted by an eligible (lead) institution. Alliances may hold only one active alliance award at a time.  Institutions partnering in an alliance may not be a formal partner in more than one alliance at the same time.  Formal partners are IHEs participating in an alliance that report enrollment and degree data and receive funding from the project.  This eligibility applies to proposals for STEM Pathways Implementation-Only Alliances, Bridge to the Baccalaureate Alliances and Louis Stokes STEM Pathways and Research Alliances.

Bridge to the Doctorate (BD) Activity Projects:  One proposal for BD support may be submitted by an eligible alliance institution.  An institution may have only one active BD award.  New proposals for additional cohorts may be submitted once the current award has expired.

Regional Foundational and Forward-Thinking Educational Research Conferences:  Only one proposal per year may be submitted by an eligible institution or organization. 

There is no limit to the number of proposals an eligible organization may submit to this program as long as each proposal pertains to a different IUCRC.

An organization may serve as a lead organization on only one proposal. Proposals that exceed the organizational limit (beyond the first submission based on timestamp) will be returned without review. No exceptions will be made. 

Full proposals involving multiple organizations may be submitted two ways:

• a single submission from a lead organization, with other collaborating organizations included as subawardees,  OR
• separate submissions from a lead organization and ONE collaborating organization, with any additional collaborating organizations included as subawardees.

See PAPPG Chapter II.D.3 for additional information on collaborative proposals.

HBCU-UP Proposals:

• An eligible institution can submit only one Implementation Project or ACE Implementation Project proposal per year. An institution may have only one active Implementation Project or ACE Implementation Project award. However, a new proposal can be submitted by an institution with an active project if that project is due to expire before new awards will be made. Also, an institution can be awarded, at most, three Implementation Projects and one ACE Implementation Project over time.

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.
