Only one preliminary proposal may be submitted per eligible institution and due date. 

Full CREST Center proposals are to be submitted only when invited by NSF in response to a successful preliminary proposal.

An institution may have only one active CREST Center award at one time, irrespective of focus area.

Institutions that have completed a Phase I or Phase II award in a disciplinary area may re-compete in other disciplinary areas that are significantly different from those of the previous award(s). To be significantly different, the new project must also have new PIs, co-PIs, and faculty investigators. The research to be supported cannot be derived from the previous award.

Institutions with active Phase I funding should submit the Phase II preliminary proposal by the due date before the full proposal is due and prior to the expiration of their Phase I award. For example, Phase I CREST Centers ending in 2025 should submit their preliminary proposals in 2023 to avoid disruptions in funding.

Only one submission per institution or organization is allowed where the institution or organization serves as the lead either on a single proposal with subawards or as the lead on a set of separately submitted collaborative proposals. There is no limit on the number of submissions per jurisdiction.

Only one submission or active award per institution or organization is allowed where the institution or organization serves as the lead either on a single proposal with subawards, or as the lead on a set of separately submitted collaborative proposals.

There is no limit on the number of preliminary proposals an organization may submit as the lead organization. Full proposals are to be submitted only if/when invited by NSF. There is no limit to participation as a partner organization or subawardee.

Although more than one organization may participate in a proposal, a single organization must accept overall management responsibility for the project. The proposal must be submitted by one organization, with funding provided to any other organization through subawards. The use of the separately submitted collaborative proposal method is not permitted.

An institution may have only one active HBCU-RISE award, irrespective of focus area. Therefore, institutions with an active HBCU-RISE award are not eligible to submit a proposal in response to this solicitation unless the active award will end prior to the proposed start date specified in the proposal. The institution is responsible for verifying if they have a current active HBCU-RISE award.

Two (2) in Track 1, one (1) in Track 2 and one (1) in Track 3 as described below. Potential PIs are advised to contact their sponsored projects office well in advance of the MRI submission window 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[2] subawardee in no more than three MRI proposals in Tracks 1 and 2 as defined below, with no more than two (2) submissions in Track 1 and no more than one (1) submission in Track 2. One (1) additional submission is permitted in the newly defined Track 3. As a result, it is now possible for an institution to submit up to four MRI proposals within the Track limits described above.

Any MRI proposal may request support for either the acquisition or development of a research instrument or an upgrade of an existing research instrument. Within their submission limit, NSF strongly encourages an organization to submit proposals for innovative development projects.

• Track 1: Track 1 MRI proposals are those that request funds from NSF greater than or equal to $100,000^[1] and less than $1,400,000.
• Track 2: Track 2 MRI proposals are those that request funds from NSF greater than or equal to $1,400,000 up to and including $4,000,000.
• Track 3 MRI proposals are those that request funds from NSF greater than or equal to $100,000^[1] and less than or equal to $4,000,000 for requests that include the purchase, installation, operation, and maintenance of equipment and instrumentation to reduce consumption of helium.

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 institution is to help ensure that there is appropriate institutional commitment necessary for responsible oversight, by the potential awardee institution, 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.E.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.

per Phase I award.

An organization may submit only one NSF SBIR/STTR Phase I proposal per submission window (e.g., November 02, 2022 - March 01, 2023). An organization must wait for a determination from NSF (e.g., Award, Decline, or Returned Without Review) on the pending NSF SBIR/STTR Phase I proposal before submitting a new proposal in the next or any subsequent window. This eligibility constraint will be strictly enforced. If an organization exceeds this limit, the first proposal received will be accepted and any additional proposals submitted will be Returned Without Review. Similar limitations will be applied to the submission of Project Pitches. Please refer to Section V.A. of the solicitation for details. Declined proposals require a new invitation to submit (via the Project Pitch process) and significant revision, while proposals Returned Without Review may be submitted using the same invited Project Pitch (assuming that the proposal is received within one year of original the Project Pitch invitation).

An organization may submit one proposal per submission window. An organization must wait for a determination from NSF (e.g., Award, Decline, or Returned Without Review) on the pending proposal before submitting a new proposal in the next window. Declined proposals require a new invitation to submit (via the Concept Outline process) and significant revision, while proposals Returned Without Review may be submitted using the same invited Concept Outline (assuming that the proposal is received within one year of the original Concept Outline invitation).

No other restrictions apply.

An eligible organization may participate in only two (2) proposals per NRT competition as lead or collaborative non-lead. All Track 1 and/or Track 2 NRT proposals will be counted toward this total limit of two proposals per organization.

Participation includes serving as a lead organization or non-lead organization on any proposal. Organizations participating only as evaluators on projects are excluded from this limitation. Proposals that exceed the organizational eligibility limit will be returned without review regardless of whether the organization on such a proposal serves as lead or non-lead collaborative organization. Only US IHEs are eligible to submit as a lead or non-lead organization. Potential PIs are advised to contact their institutional office of research regarding processes used to select proposals for submission.

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.
