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 |
---|---|---|---|
RM1 | Research and Development | Research Project with Complex Structure | To support a large-scale research project with a complex structure that cannot be appropriately categorized into an available single component activity code. The performance period may extend up to seven years but only through the established deviation request process. ICs desiring to use this activity code for programs greater than 5 years must receive OPERA prior approval through the deviation request process. |
