Activity Codes
NIH uses three-character activity codes to differentiate the wide variety of research-related programs NIH supports. The first character typically identifies the major funding category or program type. For example, activity codes for research and development often start with "R," training with "T," fellowship with "F," and career development with "K." Each institute and center (IC) participates in a subset of activity codes. Although each activity code has a broadly defined purpose, there may be differences in their use from one IC to another. Applicants should always refer to the funding opportunity for the specific requirements and details of an initiative.
Activity Code ▼ | Funding Category | Title | Description |
---|---|---|---|
RL1 | Research and Development | Linked Research project Grant | To support a discrete, specified, circumscribed project that is administratively linked to another project or projects, and to be performed by the named investigator(s) in an area representing his or her specific interest and competencies. An RL1 award may only be disaggregated from U54 application and organizations may not apply for an RL1, Linked Research Project Grant. The RL1 activity code is used in Lieu of the R01 for those programs that offer linked awards. |
