With the introduction of the new forms J, NIH letters of support will be replaced with letters of collaboration. Letters designed to endorse the application without an intent to collaborate or provide material support will no longer be permitted in NIH grant applications. Applications that continue to include letters of support after the implementation date may be returned without review.
Letters of collaboration should be limited to stating the intent to collaborate or provide material support as described in the application and should not contain endorsements or additional information about or evaluations of the proposed project. An individual letter of collaboration must not exceed 100 words. NIH encourages applicants to use the following single-sentence format for letters of collaboration.
For all applications except for fellowships:
"If the application submitted by [Organization Name and with PD/PI Name] as Program Director/Principal Investigator entitled [Grant Application Title] is selected for funding by NIH, it is my intent to collaborate and/or commit resources as detailed in the application."
For fellowship applications:
"If the fellowship application submitted by [Fellow Name] entitled [Fellowship Application Title] is selected for funding by NIH, it is my intent to collaborate and/or commit resources as detailed in the application."
