Major Research Instrumentation Program
OpenU.S. National Science Foundation
Updated: Oct 30, 2025
Summary
The Major Research Instrumentation (MRI) Program aims to enhance access to multi-user scientific and engineering instruments for research and training at U.S. higher education institutions and not-for-profit organizations. Eligible applicants include accredited Ph.D.-granting and non-Ph.D.-granting institutions, not-for-profit organizations, and consortia of these entities. Proposals can be submitted through specific tracks based on funding amounts, with a maximum of four submissions allowed per institution across the defined tracks; applicants are encouraged to consult with NSF for eligibility and submission details.
Full Description
Description
- Track 1: Track 1 MRI proposals are those that request funds from NSF greater than $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: 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 that include the purchase, installation, operation, and maintenance of equipment and instrumentation to conserve or reduce the consumption of helium. Institutions may submit no more than one Track 3 proposal. Submission of a Track 3 proposal does not impact limits that apply for Track 1 and Track 2 proposals.

Additional information
- Institutions of higher education (Ph.D.-granting and non-Ph.D.-granting), acting on behalf of their faculty members, that are accredited in and have their main campus in the United States, its territories or possessions. Distinct academic campuses (e.g., that award their own degrees, have independent administrative structures, admissions policies, alumni associations, etc.) within multi-campus systems qualify as separate submission-eligible institutions.
- Not-for-profit, non-degree-granting domestic U.S. organizations, acting on behalf of their employees, for example (but not limited to) independent museums and science centers, observatories, research laboratories and similar organizations that are directly associated with the Nation's research activities. These organizations must have an independent, permanent administrative organization (e.g., a sponsored projects office) located in the United States, its territories or possessions, and have 501(c)(3) tax status.
- To facilitate access to unique instrumentation for a broad user base of U.S. scientists and engineers, and to encourage collaboration and sharing of state-of-the-art instrumentation, the MRI program accepts proposals from consortia of organizations. Consortium proposals may be submitted as follows:
3a. Legally incorporated, not-for-profit consortia that include two or more submission-eligible organizations as described in items (1) and (2) above may submit proposals on behalf of the consortium. The cover sheet must clearly indicate the consortium nature of the proposal in the title. Such a consortium is one with an independent administrative structure (e.g., a sponsored projects office) located in the United States, its territories or possessions and have 501(c)(3) status.
3b. Submission-eligible organizations as described in items (1) and (2) above may submit, as part of their limit, proposals on behalf of consortia. The cover sheet of such a proposal must a) clearly indicate the consortium nature of the proposal in the title, and b) it must identify both a PI and co-PI(s) from at least two MRI submission-eligible organizations (items 1 and/or 2 above) as lead investigators in the consortium. These consortium proposals may also include as partners other U.S. organizations that are not eligible to submit MRI proposals. For-profit commercial organizations, especially U.S. small businesses with strong capabilities in scientific or engineering research or education, are eligible for instrument development support through subawards/subcontracts as private sector partners with submitting organizations; they may not submit proposals. Such partnerships must be substantive and meaningful, and build capacity for instrument development within MRI submission-eligible organization(s). Title to the resulting instrument should be retained by the MRI-eligible performing organization(s). Prospective PIs may contact the cognizant MRI program officer regarding organizational eligibility, and for information on other NSF funding opportunities for instrumentation; see also Section IX for a list of related NSF programs for research instrumentation. Organization Categories All MRI-eligible organizations belong to one of the following three categories:
- Ph.D.-granting institutions of higher education are accredited colleges and
