The R01 is NIH’s most commonly used grant program. It supports discrete, specified, circumscribed research projects, is generally awarded for 3-5 years, and is supported by all Institutes and Centers at the NIH.
Other grant mechanisms in the R series are targeted to smaller, more specific aims, such as pilot studies, scientific meetings, clinical trial planning, small business innovation/technology transfer, and short-term projects.
For assistance with an R grant, or to submit a sample R, contact the CCTS Research Commons (
