The success rate is the total number of grant applications that are funded in a given fiscal year divided by the number of grant applications that were peer reviewed. Success rates, computed on a fiscal year basis, indicate the percentage of reviewed research project grant applications that receive funding. For research project grants and R01s in FY 2017, NIGMS achieved a success rate of 30.6 percent and 28.3 percent, respectively. A large proportion of NIGMS' research project grants are R01s, so the success rate for R01s is usually similar to the overall research project grant success rate.
The percentile is a ranking that shows the relative position of each application's priority score among all scores assigned by a scientific review group at its last three meetings.
The success rate for R01 grants differs from the percentile ranks for R01 grants in the following ways:
NIGMS does not rely solely on a percentile cutoff or "payline" to make its funding decisions. These decisions take into account a number of additional factors, including whether the project will increase the breadth and diversity of the Institute’s research portfolio, approaches and investigators, and whether the research area is a high priority for the Institute’s mission. NIGMS staff and the National Advisory General Medical Sciences Council also carefully consider the relative value of awarding grants to laboratories with
research support in excess of $1,500,000 total costs in any year and
investigators with substantial unrestricted research support versus awarding grants to those with little or no other research support. These factors, along with the priority score, the comments in the summary statement and the advice of the Council, are considered together to make final funding decisions.
The current average size of an NIGMS R01 grant (excluding supplements) is approximately $237,000 in direct costs per year. The average competing award is also currently at about $237,000. Among the competing awards, new awards are smaller than the average and competing renewal awards are larger.
