What is the limit of support for predoctoral and postdoctoral years?
No individual trainee may receive more than 5 years of aggregate NRSA support at the predoctoral level or 3 years of support at the postdoctoral level, including any combination of support from institutional training grants and individual fellowship awards. Any extension of the total duration of trainee support at either the predoctoral or the postdoctoral level requires approval by the director of the NIH Institute or Center that supports the award.
