Activity Codes
NIH uses activity codes (e.g. R01, T32, etc.) to differentiate the wide variety of research-related programs.NIH Institutes and Centers (ICs) may vary in the way they use activity codes; not all ICs accept applications
for all types of grant programs or they apply specialized eligibility criteria.
Look closely at Funding Opportunity Announcements (FOAs) to determine which ICs participate and
the specifics of eligibility.
