Extension Policy for K99/R00 Eligibility

November 4, 2019

NIH recognizes that a lot can happen to interrupt the 4-year K99 eligibility window. Since one of the most popular reasons for extension requests involve childbirth, NIH will approve an extension of one year for childbirth, consistent with the NIH Extension Policy for Early Stage Investigator Status (ESI), effective immediately. Men, those adopting children, and same-sex partners of individuals giving birth can also apply for an extension.
