NIA offers several different career development (K) awards to postdocs who intend to transition into a faculty position. The K99 is for postdocs seeking 1-2 additional years of postdoctoral training before moving into a tenure-track position. The K22 is for postdocs who are nearly ready to transition to a tenure-track faculty position, with no additional postdoctoral training needed. The K01 is typically a career development award for faculty members, but if you’re a postdoc who has already negotiated a faculty position, the K01 might be a good fit for you as well.
The table below highlights the differences between these three awards, you should visit the individual award page as well to read more details about each award. When considering the timeline of your transition to a faculty position, remember that it takes about 9 months from the application due date to issuance of an award or letter of approval.

Which K Award is Right for Me? Examples by Career Level
Here are some typical profiles of aging research postdocs, and the best award for them:
| I am … | I should apply for… |
|---|---|
| A postdoc with a vision for research in my own lab, but I still have quite a bit to learn before I’m ready to embark on that research independently! | K99 |
| A postdoc with a strong plan for independent research in my own lab, I’m ready to enter the tenure-track faculty job market! | K22 |
| Still a postdoc right now, but I’ve accepted a faculty job offer. Or, I’m in negotiation stages and expect to start a faculty job in less than a year. | K01 |
| A postdoc who just got promoted to research scientist / instructor / another non-tenure track faculty position, and I want to continue mentored career development at my current institution. | K01 |
| An international postdoc, but I am too late to apply for the K99/R00. | Research Funding for Early Career Investigators |
