IRB Target Turnaround Times

The IRB sets target turnaround times for initial screening, screening of changes, expedited review, and producing correspondence after review. We hope that this information will help you know what to reasonably expect, and when it's reasonable to start checking in.

The other main element in the overall IRB timeline is the study team's turnaround time when the IRB requests changes. In addition, the following can have an impact.

Factors Impacting the Overall Timeline

The quality of the submission:

  • Use our (ICF/HIPAA templates)
  • See our guidance information for new studies, and...
  • Our Protocol templates for investigator-designed studies
  • Instructional video for eIRB submission
  • Whether grant/contract negotiations and any ancillary reviews are still outstanding
    • Submit to other offices in parallel whenever possible
  • How quickly the study team replies to requests for clarification or changes
  • Spikes in submissions to the IRB
Currently, the IRB has several vacancies. We are filling in partially with outside consultants, and are recruiting new hires as quickly as possible in this environment. Please see our job postings here! IRB Homepage - See Announcements at bottom

Requests for Accelerated Handling

We get these requests frequently so must evaluate them carefully. Taking items out of the queue must be for a truly urgent matter that may adversely affect study subjects. Contact the IRB Director or ADs to provide justification.

General IRB Turnaround Targets

General IRB Turnaround Targets

We always try to beat these targets, but below is a reasonable expectation. Note: Repeated calls or emails when the IRB is within our targets may delay your and others' studies.

The time to IRB review is not the same as time to approval. There are often changes requested.

All times are in business days

Note: Due to the implementation process for the new eIRB system, expect delays that may add 2 to 3 days to the following turnaround times.

Type of SubmissionIRB Staff ScreeningTime until review after receipt of complete submissionFollow up/Letter after review

Pre-screen 3-4 weeks prior to expiration (if submitted in time); sooner if Grady site

More Information

  • The IRB meets 6 times a month, and there are up to 5 new studies on each agenda.
  • Expedited review means review by one designated reviewer, instead of review at a convened meeting (does not always mean "faster").
  • Most IRB reviewers are full-time faculty/clinicians, and while they have target turnarounds, delays sometimes occur.
  • Continuing reviews will generally be held until the study is within 45 days (Full Board) or 30 days (Expedited) of expiration, to preserve more of your approval period. Studies requiring Grady ROC review are processed earlier.

[1] Studies involving procedures that may involve risk to subjects, or when drug or devices are used, generally require full board review. Amendments are reviewed at full board if they indicate a potential increase in risk to participants, or if they involve more than a "minor change" to a more-than-minimal-risk study.
