Biosketches are required for all senior/key personnel and Other Significant Contributors (OSCs). The NIH defines senior/key personnel as “individuals who contribute to the scientific development or execution of a project both substantively and measurably.” Misidentifying personnel as senior/key creates unnecessary burden for application preparation, submission of Just-in-Time information, and annual reporting requirements. The NIH defines OSCs are individuals who will contribute to the scientific development or execution of the project, but will be contributing on an “as needed” basis and/or represented a “zero person months” in measurable effort. Consultants can be considered as OSCs if they meet this definition.
