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 |
|---|---|---|---|
| SI2 | Research and Development | Intramural Clinical Scholar Research Award | This program will encourage exceptionally talented clinical researchers to conduct research in the Intramural Research Program for a specified period of time who will then be able to work with an extramural institution to develop an independent research grant application for follow-on support. This code can only be used as phase 1 (intramural) of a 2-phase intramural/extramural program. No extramural award can be issued using this activity code. NIH Intramural and OPERA prior approval is required to use this activity code. |
