Research Project Grant Application Success Rates

NIH uses success rates as a metric for describing the likelihood of a project getting funded. Success rate is defined as the number of awards divided by the number of unique applications in a fiscal year. Below, we provide NIDCR success rates for R01, R03, and R21 research project grant applications. For more information on NIH success rates please visit NIH Research Portfolio Online Reporting Tools (RePORT) Success Rates webpage.

NIDCR R01 Success Rate

Figure 1: Success rates for Type 1 and type 2 R01 applications are plotted separately. American Recovery and Reinvestment Act (ARRA) funds in 2010-2019 are not included. The high success rate for Type 2 R01s in 2010 is due to fewer submissions coupled with more awards for meritorious applications.

NIDCR R21 Success Rate

Figure 2. Success rates for R21 applications. American Recovery and Reinvestment Act (ARRA) funds in 2010-2019 are not included. The R21 data represents a 2-year running average to minimize variability due to small sample sizes.

NIDCR R03 Success Rate

Figure 3. Success rates for R03 applications. American Recovery and Reinvestment Act (ARRA) funds in 2010-2019 are not included. The R03 data represents a 2-year running average to minimize variability due to small sample sizes.
