The applicant institution will be the mentored phase (K99) institution. All institution/organization types listed above are eligible for both the mentored (K99) and independent (R00) phase, with the following exceptions: (1) Eligible agencies of the Federal government, such as the NIH intramural program, are eligible only for the mentored phase; and (2) Eligibility of organizations, other than institutions of higher education, for the R00 phase depends on the nature of the appointment, and the ability of the PD/PI to conduct independent research and apply for NIH research (R01 or R01-equivalent) grants.
Candidates for the K99/R00 are strongly encouraged to obtain confirmation of their eligibility from the relevant IC before they begin to prepare their applications. It is incumbent upon the candidate to provide evidence that they meet all of the eligibility criteria outlined below.
Any candidate with the skills, knowledge, and resources necessary to carry out the proposed research as the Program Director/Principal Investigator (PD/PI) is invited to work with his/her mentor and organization to develop an application for support. Individuals from underrepresented racial and ethnic groups as well as individuals with disabilities are always encouraged to apply for NIH support. Multiple PDs/PIs are not allowed.
K99/R00 applicants must have no more than 4 years of postdoctoral research experience as of the relevant application due date regardless of whether it is a new or resubmission application. Individuals must be in mentored, postdoctoral training positions to be eligible to apply to the K99/R00 program. If an applicant achieves independence (i.e., any faculty or non-mentored research position) before a K99 award is made, neither the K99 award, nor the R00 award, will be issued.
