According to the NIH’s Rock Talk blog:
We’re set for a major change in how you portray your body of work when applying for NIH funds. With strong support from NIH leadership, we will be rolling out a new biosketch format. The new NIH biosketch emphasizes your accomplishments instead of just a list of publications, which, as previously discussed, we questioned as the best way to showcase your scientific contributions.
The blog post provides more information and links to resources on the change.
The agency expects to roll out the new biosketch format for all grant applications received for FY 2016 funding and beyond (which generally refers to applications submitted in early 2015).
