Step 1. Are human subjects involved? (even if exempted under 45 CFR Part 46)?

Step 2. Is the information on representation of children and older adults provided?

  • If yes:
  • If no:
    • Absent (negative impact on the score, bar to award or application not reviewed)
    • End.

Step 3.

  • What is the actual representation of children, adults, and older adults?
    1. Children, adults, and older adults are included in scientifically appropriate numbers and with appropriate age ranges? (Code C1: children, adults, and older adults)
    2. All or some age ranges are excluded because one of the following exceptions applies?
      • The disease or condition does not occur in the excluded age group, or the research topic is not relevant to the excluded age group
      • The knowledge being sought in the research is already available for the excluded age group or will be obtained from another ongoing study, and an additional study will be redundant.
      • A separate age-specific study in the excluded age group is warranted and preferable. While this situation may represent a justification for excluding individuals based on age, consideration should be given to taking age differences into account in the study design, whenever feasible.
      • The study will collect or analyze data on pre-enrolled study participants and data inclusive of individuals across the lifespan are not available to address the scientific question.
      • There are laws or regulations barring the inclusion of individuals in a specific age group in research.
      • The study proposes an unacceptable risk to the excluded group, such that their participation would not be considered ethical by the local IRB, peer review, and/or NIH staff.
      • Other special cases acceptable to the review group and Institute Director.
      • (Code C2: children only; Code C3: adults and older adults only; Code C6: children and adults only; Code C7: adults only, Code C8: older adults only; Code C9: children and older adults only)
    3. Age representation in specimens or datasets cannot be accurately determined and this does not compromise the scientific objectives? (Code C4: age representation unknown)
    4. Original review occured prior to age coding policy. (Code C5: historical inactive value)

Step 4

  • Is representation of indivduals of all ages acceptable?
    • If yes:
      • Acceptable.
      • Code C1A, C2A, C3A, C4A, C5A, C6A, C7A, C8A, or C9A.
      • End.
    • If no:
      • Unacceptable
      • Code C1U, C2U, C3U, C4U, C5U, C6U, C7U, C8U, or C9U.
      • Negative impact on score.
      • End.
