Why your IRB came back "revise".

2026-05-14 · by Anjali N., MSN, RN · IRB & protocols

A revision letter is not a rejection and it is not a comment on your research. It is a numbered list of things a committee could not find, and it is answered with a document rather than an argument. Here is what those numbers usually mean.

Revise is the normal outcome

Almost nothing clears on a first pass, protocols by professionals included. The people reviewing yours are doing it unpaid, after their real jobs, working through a pile in one sitting, and a reviewer in that position asks rather than assumes.

So the letter arriving in your inbox says very little about the quality of your study. What it does say is that a reader could not locate something they are obliged to check. Read it that way and the whole exercise stops being personal and becomes clerical, which is a much better mood to answer it in.

The four requests behind most letters

Different boards use different templates, but the substance clusters. Recognising which of these you have received tells you what to change.

Write a response memo, not a letter

The single most useful habit in this process is answering in the board's own numbering. Take point one, restate it in a line, say what changed and where, then paste the new wording in full so nobody has to open an attachment to see it. Then point two.

That format matters because your reader is doing the same job again, at night, with a stack. Anything that forces them to hunt costs you their patience and often a whole cycle. A memo they can check in four minutes gets checked in four minutes.

Attach the revised documents with the changes visibly marked, and keep a clean copy alongside for the file. Boards differ on which they prefer, so send both and let them pick.

The mistake that costs a cycle

Arguing. It is the most natural response and it is the expensive one. When a member asks for a clearer statement of risk, they are not inviting a defence of the original sentence, they are telling you what has to be in the document before they can approve it.

You may well be right that the first version covered it. Being right does not get you approved; producing the sentence they asked for does. Save the reasoning for the cover note, one line, and put the change itself front and centre.

The related trap is answering only the points you agree with. An unaddressed number reads as refusal and comes straight back. If a request genuinely cannot be met, say why in a sentence and propose the nearest thing you can do.

The calendar is what actually costs you

Committees meet on fixed dates with submission deadlines in front of them. A flawless response landing the day after a cutoff waits for the next meeting, which can be a month, and no amount of quality shortens that.

So find the next two meeting dates before you start writing, and work backwards from the earlier one. Assume one more round after this, because most protocols get two. Students who plan for the calendar finish a term ahead of students who plan only for the writing.

If your chapters are stalling while all this runs, keep them moving in parallel rather than in sequence. Our research desk exists for exactly that overlap, but the discipline works whether you use us or not: never let the protocol become the only thing happening.

Questions people actually ask.

Does a revision letter hurt my chances?

No, and it carries no memory. Boards do not track how many rounds a protocol took and nobody reads the count afterwards. What a letter costs is calendar time, which is why the response should go back inside the week rather than sitting while you decide how to feel about it. Two rounds is entirely ordinary.

How quickly should I send the response back?

Inside a week, and preferably inside three days. The writing itself rarely takes more than an afternoon once you stop arguing with the points, and everything after that is dead time against a meeting calendar you do not control. Students routinely lose a month by sitting with a letter while they process how it felt to receive it.

Should I mark up the documents or send clean copies?

Send both, in one message. Some committees want to see precisely what moved and read a tracked version; others find markup distracting and prefer the finished document. Providing each removes a decision from your reviewer and eliminates one entire category of follow-up request. Name the files clearly enough that nobody has to open them to tell which is which.

The letter asks for something my design cannot do. Now what?

Say so directly, in one sentence, and offer the closest workable alternative rather than leaving the point blank. Silence on a numbered item reads as refusal and brings the packet straight back. Committees are generally reasonable about genuine constraints when the constraint is explained and something is proposed in its place.
