You hit submit on your IRB application. Now what?
If you’re a nonprofit staffer, community organizer, or first-time evaluator, that question can feel surprisingly hard to answer. Unlike a grant application, where you at least know the notification date, IRB (Institutional Review Board) review can feel like a black box. You send your protocol into a portal or an inbox, and then… silence. No dashboard or percentage bar to check, just you and your anxieties, waiting.
Most IRB guidance is written for university faculty who submit protocols every year, not for community-based researchers doing this for the first time or only every few years. So today, we’re mapping out what happens after you submit an IRB application – step by step – and giving you a checklist of what reviewers are looking for so you can stop guessing.
Why The Waiting Period Feels So Opaque
Institutional Review Boards exist to protect the people participating in your research, a responsibility that traces back to the National Research Act of 1974 and decades of research oversight that followed. That protective mission is exactly why the process involves multiple checkpoints instead of a single yes/no click. Each checkpoint exists to catch something a rushed review might miss.
If you’re working with an independent IRB rather than a university-affiliated one, the process is often faster and more accessible, but the underlying steps are largely the same everywhere.
The IRB Timeline, Step by Step
1. Administrative screening (typically a few business days)
Before anyone evaluates the ethics of your study, someone checks that your application is complete: consent forms attached, recruitment materials included, data management plan present. Incomplete applications get sent back before substantive review even begins, which is one of the most avoidable sources of delay.
2. Review-type determination
A reviewer or administrator decides whether your study qualifies as exempt, expedited, or full board, based on risk level, population, and study design. This decision shapes everything downstream. Research involving vulnerable populations, sensitive topics, or more than minimal risk is more likely to be routed to full board review.
3. Expedited review (often 1–2 weeks)
Minimal-risk studies are typically reviewed by one or two designated reviewers rather than the entire board, and can be evaluated on a rolling basis rather than waiting for a scheduled meeting.
4. Full board review (often several weeks to a few months)
Higher-risk studies are reviewed at a convened board meeting, which usually happens monthly. Miss the submission deadline for a given meeting, and your protocol waits for the next one.
5. Stipulations and revisions
Almost no protocol sails through untouched. Reviewers commonly request clarifications to consent language, recruitment scripts, or data handling procedures. This is the stage where timelines most often stretch, since the review clock effectively pauses until you respond.
In a study of how Veterans Affairs used IRBs, 80% of the most severe delays were attributable to investigators being slow to respond to requested changes — not to the IRB. Turning around revisions quickly is the single most controllable lever you have.
6. Final determination
You receive an approval letter, a conditional approval pending minor fixes, or (rarely, if the concerns are significant) a request to resubmit. Nothing involving human subjects — recruitment, consent, data collection — should begin before this letter arrives.
7. Ongoing oversight
Approval isn’t a one-time event. Most approvals are tied to a project period, often about a year, after which you’ll need continuing review or a study closeout. Any change to your protocol along the way — a new recruitment site, an added survey question — typically requires an addendum before you implement it.
What Your Reviewer Is Checking For
Reviewers aren’t grading your writing; they’re pattern-matching your application against a specific set of protections. A checklist that mirrors what most reviewers look for:
- A clearly defined, appropriately protected population
Does your application name who’s involved and address any added vulnerability — age, language, power dynamics, immigration status — honestly rather than glossing over it?
- Consent that matches your participants’ actual context, not a boilerplate form.
This includes literacy level, language, and how consent is documented. We dig deeper into this in Data Collection Prep 101. - A concrete data management plan
How data is stored, who can access it, how and when it’s destroyed, and whether it will be shared with partners in ways participants were told about. - Evidence of community review or partnership, where relevant
Reviewers increasingly want to see that the people affected by the research had some say in how it’s designed, a piece we unpack in our nonprofit community research compliance framework. - Recruitment materials and incentives
that don’t pressure or coerce participation, especially for populations with less power relative to the researcher. - Documented training
for everyone with a substantive role in the study, including community partners and contracted evaluators — not just the lead researcher. Our human subjects research certification covers what this typically requires!
How to Shave Weeks Off Your IRB Approval Timeline
The best thing you can do to speed up your IRB approve is to respond to revision requests quickly, since slow investigator response is the most common cause of extreme delays. You’ll also want to submit complete materials the first time, since incomplete applications restart the clock.
You should also know your population and risk level honestly before you submit, since under- or overselling risk is a common reason applications get bounced back or routed to a slower review path than necessary.
Planning + Prepping Your IRB Application
Timelines vary by IRB, but here’s a realistic reference point: through VIRB, Viable Insights’ independent IRB built specifically for evaluators and community-based organizations, expedited applications are typically reviewed in 7–10 days, and full board reviews in up to 21 days. Addendums to already-approved projects usually turn around in 1–2 days. If you’re not even sure your project needs IRB review, that initial determination is free.
If you’re staring down a blank IRB portal and don’t know where to start, that’s exactly the gap we built VIRB to close. Start with a conversation and we’ll help you understand what your project actually requires before you spend hours on paperwork you may not need.
