NIMH is the National Institute of Mental Health, the NIH institute that funds research on mental illnesses. Its own funding pages describe it as the largest funder of research on mental disorders in the world. This guide shows how NIMH sorts its funding into mechanisms (research, career, training, center), how a Program Announcement differs from a Request for Applications, and who to contact before you write. Everything below is as described on the official NIMH pages on 2026-10-29. NIMH is not NIMHD: the National Institute on Minority Health and Health Disparities is a separate institute with its own funding.

Suggested question: “What does NIMH stand for?”
What it is and who runs it
NIMH is part of the National Institutes of Health, a component of the U.S. Department of Health and Human Services. Its stated aim is transforming the understanding and treatment of mental illnesses, and it was established under the Mental Health Act of 1946. The institute has an extramural side that funds research at universities and other institutions, and an intramural side: the Intramural Research Program, based in Bethesda, Maryland, with about 600 scientists.
The NIMH overview page says the institute supports more than 3,500 research grants and contracts annually and is organized into five scientific funding Divisions: neuroscience, translational research, services and intervention research, AIDS research, and data science.
Eligibility (summary, with the official source)
NIMH does not publish one general eligibility rule for all of its grants. Eligibility is set announcement by announcement, so the controlling text is the funding opportunity you plan to answer. The NIMH mechanisms page directs applicants to the specific Program Announcement (PA) or Request for Applications (RFA), where program officer and grants management contacts are listed in section VII. For early-career awards, NIMH’s early-career page advises reviewing the career award policy updates before submitting and consulting a program officer well in advance of preparing an application.

What it funds or requires
NIMH groups its grants into four families. The table shows them as the mechanisms page describes them.
| Family | What the NIMH page says |
|---|---|
| Research (R series) | Research grants. The page notes the family includes SBIR awards. |
| Career development (K series) | Career awards. NIMH’s early-career page lists K01 (Mentored Research Scientist Development Award), K08 (Mentored Clinical Scientist Research Career Development Award) and K23 (Mentored Patient-Oriented Research Career Development Award). |
| Fellowships and training (F and T series) | Individual fellowships and institutional training grants. |
| Program project and center (P series) | Program project and center grants. |
For what the letters mean across all of NIH, see the NIH activity codes entry.
Application or compliance steps
Choose the right kind of announcement
The two announcement types behave differently, and the choice drives the rest of your plan.
| Your situation | NIMH route | What the page says |
|---|---|---|
| Your topic fits an area NIMH has flagged as a priority | Program Announcement (PA) | Identifies areas of increased priority and/or emphasis on particular funding mechanisms for a specific area of science. Usually accepted on standard receipt dates, on an ongoing basis, and active for three years from release. |
| The area needs special referral or a special review group | PAR (a type of PA) | Uses special referral guidelines; a special review group is formed. |
| You want a PA that carries dedicated money | PAS (a type of PA) | Includes set-aside funds. |
| A narrowly defined area where NIH institutes have reserved funds | Request for Applications (RFA) | Funds are set aside by one or more NIH institutes. Usually a single receipt date stated in the announcement. |
| You are early in your research career | K01, K08 or K23 | Listed on the NIMH early-career page; read the career award policy updates first. |
Contact the right person
Each announcement lists two kinds of contact in section VII. Program officers give technical help with the application. Grants management contacts help with preparing your budget. Send scientific-fit questions to the first and budget questions to the second.
Find the opportunity and read the full text
NIMH’s funding page links to all NIMH and cross-NIH funding opportunities (PAs, RFAs and policy notices) and covers writing and submitting an application and how the review process works. NIH publishes its announcements in the NIH Guide for Grants and Contracts.
Typical timeline phases
The NIMH pages describe phases, not calendar dates, so plan around the type of announcement you pick.
- Before you write. Talk to a program officer well in advance of preparing the application, as NIMH advises for early-career awards.
- Receipt. A PA is usually accepted on standard receipt dates, on an ongoing basis. An RFA usually has a single receipt date set in the announcement. See NIH standard due dates.
- Review. RFA applications are usually reviewed by a Special Emphasis Panel that NIMH convenes once for that opportunity. PARs go to a special review group.
- Active window. A PA stays active for three years from release unless the announcement sets an expiration date or NIMH deactivates it.
Common mistakes
- Treating a PA like an RFA. A PA is continuous and lasts three years; an RFA usually has one receipt date and set-aside funds. Check which one you are answering before you plan the submission.
- Writing before talking to a program officer. NIMH advises consulting one well in advance of preparing an application.
- Skipping the policy updates for career awards. NIMH strongly encourages reviewing career award policy updates before submitting a K application.
- Sending budget questions to the program officer. Section VII separates technical help (program officers) from budget help (grants management contacts).
- Mixing up NIMH and NIMHD. They are different institutes.
- Quoting a payline as a rule. Our FY2026 payline guide records that NIMH historically published a numeric percentile payline, generally with a separate ESI figure, and that no fixed FY2026 percentile payline applies under the Unified Funding Strategy.

FAQ
What does NIMH stand for?
The National Institute of Mental Health. It is part of the National Institutes of Health.
What does NIMH fund?
Research grants (R series, including SBIR), career awards (K series), fellowships and training grants (F and T series) and program project and center grants (P series), according to its mechanisms page.
What is the difference between a PA and an RFA at NIMH?
A PA flags areas of increased priority, is usually accepted on an ongoing basis on standard receipt dates, and stays active for three years from release. An RFA targets a narrower area with set-aside funds and usually has a single receipt date.
Who do I contact with questions?
