The maximum number of years an individual can receive NRSA (National Research Service Award) support (including NIOSH traineeships and NIH Fellowships from all schools attended) is: five years pre-doctoral and three years post-doctoral (for both institutional and individual awards), unless a waiver is granted.
Yes, but students receiving a stipend (plus T&F) during the academic year may be limited to how much they can work. In the summer, employment will be supplemented only up to a GSR appointment at 100% (Northern California ERC policy).
