Public Health Service funds may not be used to supplement an NRSA stipend. Trainees are required to devote fulltime effort to the training program. However trainees may receive separate salary from an NIH grant when employed for services, such as laboratory technical assistance, on a limited part-time basis. Part-time is considered up to 25% time ( e.g., 10 hours per week). Compensation may not be paid from a research grant that supports the same research that is part of the trainee’s planned training experience. Under no circumstances may the employment interfere with, detract from, or prolong the trainee’s approved NRSA training program.
Training PD/PIs must approve all instances of employment on research grants to verify that the circumstances will not detract from or prolong the approved training program.
For additional information see the NIH Grants Policy Statement, Section 11.3.10.2 Compensation.
