Rigor and Reproducibility (R&R) is the the strict application of the scientific method to ensure unbiased and well-controlled experimental design, methodology, analysis, interpretation and reporting of results.


The National Institutes of Health and other funding agencies have integrated the need to address Rigor and Reproducibility (R&R) in grant applications for several years. The goals of R&R integration into applications is to ensure that the best and most rigorous science is being conducted, highlight the need to describe details that may have been previously overlooked, and highlight the need to consider such details while minimizing burden.

Junior scientists must be trained in proper methods to ensure Rigor and Reproducibility, and senior scientists may need to be trained or reminded of the concepts encompassing R&R.

The NIH has prepared several infographics to assist researchers in meeting R&R requirements in applications.
