Senior/Key Personnel also referred to as the Program Director or PD/PI are individuals who contribute to the scientific development or execution of a project in a substantive, measurable way. Key Personnel must devote measurable Effort to the project. “Zero percent” Effort or “as needed” are not acceptable levels of involvement for those designated as Senior/Key Personnel.

The prior approval requirement for changes in status of personnel applies to senior/key personnel.

Individuals that do not have a specified measurable Effort but are nevertheless contributing to the scientific development or execution of the project should be listed as Other Significant Contributors. These individuals are listed at “Effort of Zero Months or % Effort” and on an “as needed” basis. Individuals with measurable Effort may not be listed as Other Significant Contributors.

If an award is made, Other Support information would be required of all individuals designated as Key Personnel and any changes in funding and overlap for Key Personnel must be tracked and reported. This is not the case for Other Significant Contributors as considerations of overlap do not apply to these individuals.
