How can I find out the success rates for different institutes and programs?
The Research Portfolio Online Reporting Tool provides a link to success rates http://report.nih.gov/index.aspx. Success rates are shown by specific activity codes (mechanisms). The Small Business Program consists of two Phases. The STTR Phase I uses the R41 mechanism and Phase II uses the R42 mechanism. The SBIR program Phase I uses the R43 mechanism and Phase II uses the R44 mechanism.
