Research Animals Involvement Codes

Due to current HHS and NIH restructuring, some content on niaid.nih.gov is not being updated regularly. Please refer to clinicaltrials.gov and nih.gov for the most up-to-date information on NIH research.

NIH uses the following codes to indicate the extent of research animal involvement within a grant application. They appear on applicants’ summary statements and on the grants management and program officer worksheets in IMPAC.

  • Code 10 — No live vertebrate animals involved
  • Code 20 — Vertebrate animals involved, administrative review required
  • Code 30 — Vertebrate animals involved, no SRG concerns noted
  • Code 35 — For institutional training grant trainees working on mentored projects that involve vertebrate animals, Animal Welfare Assurance required just-in-time.
  • Code 44 — Vertebrate animals involved, SRG concerns noted
  • Code 46 — Vertebrate animals involved, method of euthanasia must be resolved with OLAW prior to award. Restricted award not allowed unless resolved.
  • Code 48 — Conditional award with terms and conditions
  • Code 54 — Concerns resolved, conditions removed
