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 |
|---|---|---|---|
| F05 | Research Training and Career Development | International Research Fellowships (FIC) | To provide collaborative research opportunities for qualified non-immigrant alien scientists who hold a doctoral degree or its equivalent in one of the biomedical or behavioral sciences. |
| F30 | Research Training and Career Development | Individual Predoctoral NRSA for M.D./Ph.D. Fellowships | Individual fellowships for predoctoral training which leads to the combined M.D./Ph.D. degrees. |
| F37 | Research Training and Career Development | Medical Informatics Fellowships | To provide training to individuals in the synthesis, organization, and management of knowledge. The training should be interdisciplinary - involving medicine, biotechnology, and cognitive sciences, information science, and computer science. |
| F38 | Research Training and Career Development | Applied Medical Informatics Fellowships | To provide opportunities for scientists to make major changes in the direction of research careers for the purpose of engaging in the synthesis, organization, and management of knowledge. |
| FM1 | Research Training and Career Development | Fellowship for Intramural Dual-Degree Scientists (FIDDS) | To provide predoctoral individuals with training which leads to the combined degrees (e.g., MD/PhD) for trainees completing PhD dissertation research in NIH intramural labs. |
