The length of time for a study to be approved varies according to a number of factors.

  • Study classification (as full board or delegated) is a primary determinant, as full board reviews generally take longer
  • Complexity of the study
  • Risks involved
  • Availability of expert reviewers
  • Time taken by investigators to respond to the REB
