Multiproject Awards SOP

Lock icon: This link will not work for public visitors.Some links will work for NIAID staff only.

This standard operating procedure (SOP) includes the following sections: Purpose, Procedure, Contacts, and Links.


To provide grant funding to at least two related research projects.


You may apply for a multiproject grant in one the following two ways:

  • Respond to a P01, P30, P50, or U19 request for applications (RFA).
  • Submit an application for an investigator-initiated P01 program project grant.

Multi​project grant types include:

  • P01 grant—multidisciplinary, long-term program headed by a PI or PIs who bring in other investigators to conduct research projects and share resources. For an investigator-initiated application, go to the NIAID Investigator-Initiated Program Project Applications (P01) FOA.
  • P30 grant—center core grant that supports shared resources and facilities for a multidisciplinary research team or group of investigators focusing on a common research topic.
  • P50 grant—specialized center award that supports a multidisciplinary group of investigators who share a common research topic.
  • U19 cooperative agreement—award for multidisciplinary projects that require substantial involvement from NIAID staff. See our description of Substantial Staff Involvement at Determining When to Use a Cooperative Agreement.
  • U54 cooperative agreement—support for research and development from basic to clinical, including ancillary supportive activities that create a multidisciplinary focus on a disease or a biomedical problem. Centers may also serve as regional or national resources for special research purposes.
  • UM1 cooperative agreement—large-scale cooperative agreements involving complex clinical trials with multiple components, e.g., clinical networks.

Please note that NIH's big grant policy applies to multiproject applications, as described below.


  • If you are responding to an RFA or program announcement, read it thoroughly for eligibility conditions.
  • Read the Guidance for Preparing a Multiproject Research Application for NIAID-specific instructions.
  • For an investigator-initiated P01 application, contact an NIAID program officer when still in the planning stage to assess the likelihood of our approval of your idea.
    • NIAID must approve your application before you apply, indicating that we agree to allow Center for Scientific Review to assign it here for possible funding.
    • Your application must include a cover letter from an NIAID program officer that approves the submission.
    • For an overview on submitting an application, see P01 Program Project Grants.
  • For any multiproject application, you must get an NIAID program officer's approval six weeks before submitting if your application requests direct costs of $500,000 or more in any year of the grant, even if none of the individual projects request that much.
    • If you are requesting close to $500,000, read our Big Grants SOP for guidance.
    • Even if you plan to request under $500,000, we strongly encourage you to discuss your idea with an NIAID program officer when still in the planning stage.

Program Staff

  • Document your approval by following the procedures in the Big Grants SOP.
